The disclosure relates to the technical field of medical device, and more particularly to a monitoring system, atrial fibrillation comprehensive management method and monitoring data display method.
AF, short for Atrial fibrillation, is one of the most common arrhythmias in cardiology. The incidence of atrial fibrillation gradually increases with age, reaching 7.5% in people over 80 years old. Atrial fibrillation is extremely common in cardiac intensive care, for example, the incidence of atrial fibrillation in patients with severe heart failure is as high as 55%. To detect and evaluate atrial fibrillation in a timely manner, medical staff often use bedside monitors to continuously monitor patients in real-time. The existing monitoring system usually only detects and warns the atrial fibrillation. For example, when the monitor detects the atrial fibrillation on the electrocardiogram through backend algorithms, it automatically pops up a string of “atrial fibrillation” in the alarm area and reminds medical staff to pay attention through sound and light indications. When atrial fibrillation stops and sinus rhythm resumes, the string of “atrial fibrillation stop” automatically pops up in the alarm area. In addition to the real-time alarms mentioned above, medical staff can also browse historical alarm data through the event list in the review interface. However, medical staff cannot make a comprehensive determination of patient solely based on atrial fibrillation alarms and electrocardiogram waveforms at the occurrence time of atrial fibrillation, so the efficiency of atrial fibrillation management by medical staff is relatively low.
This disclosure mainly provides a monitoring system, an atrial fibrillation comprehensive management method, and a monitoring data display method to improve the efficiency of atrial fibrillation management.

The monitoring system, the atrial fibrillation comprehensive management method and the monitoring data display method provided by this disclosure, present information for atrial fibrillation event, vital sign parameter, atrial fibrillation burden and the likes, in a centralized manner through the design of the AF View, so as to help the medical staff to systematically evaluate the physical state of patient.
As shown in
The input device 40 is configured to receive input from a user (usually an operator). For example, one or more of a mouse, a keyboard, a touch display, a trackball, a joystick, or the likes may be configured to receive instructions inputted by a user, or the likes. Users can perform input operation through the input device 40.
The display device 30 is configured to output information, such as visual information. Display device 30 can be a display device that only has display functions, or can be a touch-control display device. It can be seen that the display device 30 and the input device 40 are human-machine interaction devices of the monitoring system. The human-machine interaction device can not only receive user inputted instructions, but also display visual information.
The signal acquisition device 10 is configured to acquire monitoring data, such as monitoring data of at least two vital sign parameters of a patient, wherein the at least two vital sign parameters include electrocardiogram parameter(s) (electrocardiogram signals).
The monitoring system can be any of: a monitor, a local central station, a remote central station, a cloud service system, or a mobile terminal, and the corresponding signal acquisition device 10 acquires the monitoring data in different ways. For example, if the monitoring system is a monitor, the signal acquisition device 10 can use sensors to monitor the vital sign parameters of the patient to obtain monitoring data of the vital sign parameter. The monitoring data of the vital sign parameter can include at least one of: types of vital sign parameters (such as at least one type of: ECG, respiration, non-invasive blood pressure, oxygen saturation, pulse, body temperature, invasive blood pressure, carbon dioxide at end respiratory, respiratory mechanics, anesthetic gas, cardiac output, Bispectral index of EEG, etc.), values of vital sign parameters, and trends of changes of values of vital sign parameters. For example, the monitoring system can be a local central station, a remote central station, a cloud service system, or a mobile terminal, then the signal acquisition device 10 can be a communication device or interface configured to communicate with the monitor to obtain the aforementioned monitoring data from the monitor.
The processor 20 can be constructed to detect atrial fibrillation according to the monitoring data acquired by the signal acquisition device 10 and obtain an atrial fibrillation analysis result, which at least includes information of an atrial fibrillation event which occurs in the patient. Of course, since the existing monitor can record the atrial fibrillation event, the processor 20 can also acquire information of the atrial fibrillation event which occurs in the patient, from the monitor through the signal acquisition device 10. The processor 20 generates an atrial fibrillation comprehensive view according to the information of the atrial fibrillation event and the monitoring data of at least two vital sign parameters, and outputs the atrial fibrillation comprehensive view. The processor 20 outputs the atrial fibrillation comprehensive view, such as through displaying the atrial fibrillation comprehensive view, outputting an electronic overview report, and printing a paper overview report through a connected printing device. In this embodiment, displaying the atrial fibrillation comprehensive view is used as an example for explanation, as shown in
Trend graph is also known as transition diagram, run graph, chain diagram, trend graph, and so on. The trend graph can be configured to reflect the relationship between one or more variables and time, that is, the trend of the development of one or more variables over time. For example, a trend graph can use time as the horizontal axis and the observed variable as the vertical axis to observe the trends and/or biases of changes and developments of the variable. The time on the horizontal axis can be seconds, minutes, hours, days, months, years, etc., and each time point should be continuous and uninterrupted. The observation variable on the vertical axis can be absolute quantity/absolute value, average value, incidence, etc. In this disclosure, the trend graphs of the vital sign parameters can be configured to reflect the trend of a certain vital sign parameter over time. For example, the parameter value of the vital sign parameter continuously changes over time. The parameter value can be either absolute value which are acquired at a certain sampling rate or average values which are acquired at a certain sampling rate and calculated at each fixed time period. Therefore, for vital sign parameters, the “variable” in the trend graph is usually the parameter value of the vital sign parameter. The trend graph of the atrial fibrillation event can be configured to reflect the trend of the atrial fibrillation event over time, such as the occurrence pattern, development trend, incidence, trend, and so on. Here, “incidence” can be an occurrence frequency of event within a time period of minimum unit, while the occurrence pattern, development trend, trend, etc., are not limited to the occurrence frequency, but can be marked according to the actual situation of the event. For example, for each atrial fibrillation event, special graphics/symbols are configured to mark it. When the atrial fibrillation event is a continuous and long-term atrial fibrillation event, the occurrence time duration of the atrial fibrillation event can be reflected by a spanning length of the horizontal axis (i.e., timeline) using graphics/symbols. In the following, the occurrence patterns, development trends, incidences, trends, and so on of atrial fibrillation events reflected in various trend graphs are described in conjunction with
The trend graphs 810 of the at least two vital sign parameters are configured to show the changes of at least two vital sign parameters during the preset atrial fibrillation monitoring period. That is, the trend graph 810 of vital sign parameter is configured to display the changes of this vital sign parameter during the preset atrial fibrillation monitoring period. The trend graph of vital sign parameter displayed in the atrial fibrillation comprehensive view can include at least one of: a trend graph of heart rate, a trend graph of pulse rate, a trend graph of blood oxygen, a trend graph of non-invasive blood pressure, a trend graph of invasive blood pressure, a trend graph of respiration, a trend graph of body temperature, a trend graph of cardiac output per stroke, a trend graph of cardiac output, a trend graph of ST segment of electrocardiogram, a trend graph of QT interval of electrocardiogram, a trend graph of blood sugar, a trend graph of cerebral oxygen and a trend graph of urine volume. The trend graph of vital sign parameter can reflect the trend of change of vital sign parameter. It can be one of a curve graph, a histogram, a bar graph, a box graph, a scatter graph, and a broken line graph, or various combinations of the curve graph, histogram, bar graph, box graph, scatter graph, and broken line graph. In this embodiment, the trend graph 810 of vital sign parameter is illustrated using a curve graph as an example.
The trend graph 820 of the atrial fibrillation event is configured to present the atrial fibrillation event that occurs in the patient during the preset atrial fibrillation monitoring period, for example, to present changes in occurrence count and/or frequency of atrial fibrillation events during the preset atrial fibrillation monitoring period. The trend graph 820 of the atrial fibrillation event can reflect the trend of change of the atrial fibrillation event. It can be one of curve graph, histogram, bar graph, box graph, scatter graph, line graph, or various combinations of curve graph, histogram, bar graph, box graph, scatter graph, and a broken line graph. Through the trend graph 820 of the atrial fibrillation event, doctors can see whether the atrial fibrillation occurs during the time period they want to pay attention to, the distribution (frequency and time duration) of the atrial fibrillation event, and the occurrence or non-occurrence of atrial fibrillation, which is very convenient.
The atrial fibrillation burden graph 830 is configured to present the atrial fibrillation burden for at least one time period of minimum unit during the preset atrial fibrillation monitoring period. By using the atrial fibrillation burden graph 830, the changes of burden between each time period of minimum unit can be directly quantified. Doctors can see an accumulation degree of atrial fibrillation and specific amount of the burden, which is very convenient. The time period of minimum unit can be automatically preset by the system, or can be inputted or modified by the user. In the embodiment shown in
Moreover, the trend graphs 810 of the at least two vital sign parameters, as well as the trend graph 820 of the atrial fibrillation event, and the atrial fibrillation burden graphs 830, are displayed simultaneously to facilitate the joint presentation of a correlation between at least two of: at least one vital sign parameter, the atrial fibrillation event occurs in the patient, and the atrial fibrillation burden, at any one or more time points or within any one or more time periods during the preset atrial fibrillation monitoring period.
Traditional monitoring devices are mainly limited to event alarms and reviews for atrial fibrillation management, and the reviewed content is mostly limited to simply presentation of the time point of alarm in the review list or provision of typical parameter (usually electrocardiogram) waveform(s) for user to view. This disclosure provides a more comprehensive method for managing atrial fibrillation according to electrocardiogram parameters, involving the joint presentation of vital sign parameter, atrial fibrillation event, and atrial fibrillation burden, and the interconnection and organic combination of various kinds of information. It can be seen that doctors can understand the comprehensive situation of patient through the atrial fibrillation comprehensive view, which facilitates rapid response measures and improves the efficiency of atrial fibrillation management.
As shown in
The process for atrial fibrillation comprehensive management through each unit of the processor 20 is shown in
In step 1, the atrial fibrillation analysis unit 220 acquires monitoring data of at least two vital sign parameters of a patient through the signal acquisition device 10, according to a parameter configuration of the atrial fibrillation configuration unit 210. The acquired monitoring data of the vital sign parameter includes monitoring data of electrocardiogram parameter(s). There are various ways to acquire monitoring data of the vital sign parameter, such as to acquire real-time monitoring data in method 1, and acquiring monitoring data during the preset atrial fibrillation monitoring period in method 2, which are explained below.
In method 1, the atrial fibrillation analysis unit 220 acquires real-time monitoring data of at least two vital sign parameters of the patient through the signal acquisition device 10. Take a sensor as an example of the signal acquisition device 10 for explanation. The sensor acquires and preprocesses the monitoring data of the vital sign parameter of the patient, including electrocardiogram parameters of one lead, to obtain corresponding real-time monitoring data. Take a communication device or interface as an example of the signal acquisition device 10 for explanation. The atrial fibrillation analysis unit 220 acquires the real-time monitoring data of the vital sign parameter from the monitor through the communication device or interface. By continuously acquiring the real-time monitoring data, the trend graph of the atrial fibrillation event can ultimately present various data within the preset atrial fibrillation monitoring period. The atrial fibrillation analysis unit 220 is further configured to display real-time electrocardiogram waveforms through the display device 30 according to the real-time monitoring data of electrocardiogram parameters, as shown in
In method 2, the atrial fibrillation analysis unit 220 acquires the monitoring data of at least two vital sign parameters of the patient during the preset atrial fibrillation monitoring period through the signal acquisition device 10. Similarly, take a sensor as an example of the signal acquisition device 10 for explanation. The sensor acquires and preprocesses the monitoring data of the vital sign parameter of the patient during the preset atrial fibrillation monitoring period. Take a communication device or interface as an example of the signal acquisition device 10 for explanation. The atrial fibrillation analysis unit 220 acquires monitoring data of the vital sign parameter during the preset atrial fibrillation monitoring period, from the monitor through the communication device or interface. By obtaining monitoring data for various vital sign parameters during the atrial fibrillation monitoring period at one time, the trend graph of atrial fibrillation event can ultimately present various data during the preset atrial fibrillation monitoring period. The preset atrial fibrillation monitoring period can be automatically preset by the system. For example, the preset atrial fibrillation monitoring period can be a pre-stored atrial fibrillation monitoring period in the atrial fibrillation configuration unit 210, or can be inputted or modified by the user. For example, the atrial fibrillation configuration unit 210 provides a setting interface through the display device, as shown in
Of course, the first and second methods are only for example, and there may be other methods. This disclosure does not limit the acquisition of monitoring data of vital sign parameter, as long as the data required for the atrial fibrillation comprehensive view can be provided.
In step 2, information of an atrial fibrillation event which occurs in the patient is acquired. There can be multiple methods, for example, if step 1 acquires the real-time monitoring data, the atrial fibrillation analysis unit 220 detects atrial fibrillation according to the acquired real-time monitoring data to obtain an atrial fibrillation analysis result, which at least includes the information of the atrial fibrillation event which occurs in the patient. Specifically, the atrial fibrillation analysis result can be obtained by the atrial fibrillation detection according to the monitoring data of electrocardiogram parameters or according to the monitoring data of other parameters, such as blood oxygen parameters, invasive blood pressure, and/or non-invasive blood pressure. The previous is explained in this embodiment. The atrial fibrillation analysis unit 220 acquires the real-time monitoring data of the electrocardiogram parameters of the patient through the signal acquisition device 10. The atrial fibrillation analysis unit 220 detects the atrial fibrillation according to the real-time monitoring data of the electrocardiogram parameters. If atrial fibrillation occurs, it generates information of the atrial fibrillation event and time duration of the atrial fibrillation. For example, the atrial fibrillation analysis unit 220 performs noise processing on the real-time monitoring data of electrocardiogram parameters; performs a P-wave analysis to determine existence, inexistence, starting and ending points, peak points, etc., of P-waves; performs F fibrillation wave analysis to determine existence and inexistence of the f-fibrillation wave; performs an irregularity analysis of RR interval; and performs heart beat classification to obtain heart beat classification result which includes: sinus, atrial, ventricular, and other categories. Specifically, a length of the RR interval is calculated based on adjacent R-waves, and the reciprocal of the length is the heart rate, then an irregularity analysis is performed on a sequence composed of RR intervals within a predetermined time period to determine whether the current paragraph of heart rate is absolutely uneven. Through one or more of the above analyses, information of atrial fibrillation event which occurs in the patient can be obtained, and the information of the atrial fibrillation event, such as the start and stop time points of the atrial fibrillation event, can be stored. The atrial fibrillation analysis unit 220 outputs the information of the atrial fibrillation event to the atrial fibrillation alarm unit 230 and the atrial fibrillation burden display unit 240. One atrial fibrillation event is one atrial fibrillation, which also corresponds to one atrial fibrillation alarm.
The monitoring system can further include buzzers, speakers, and/or warning lights. When the atrial fibrillation alarm unit 230 receives the information of the atrial fibrillation event, it indicates the atrial fibrillation occurs. The buzzers and speakers can sound an alarm indication, or the warning lights can give an alarm indication through a warning light. The display device can also display atrial fibrillation alarm information, such as displaying graphic text (an alarm string displayed in real-time in the alarm area at the top of the display interface). The alarm indication for the start and end of the atrial fibrillation can be sent to the user through the above alarm methods. As shown in
The atrial fibrillation burden display unit 240 receives the information of the atrial fibrillation event outputted by the atrial fibrillation analysis unit 220, calculates the time duration of the atrial fibrillation according to the start and stop time points of the atrial fibrillation, and then calculates a real time atrial fibrillation burden according to the time duration of the atrial fibrillation and a preset update cycle. There are many methods to define the atrial fibrillation burden, such as the longest time duration of the atrial fibrillation which occurs within a preset update cycle (a preset time period), occurrence count of the atrial fibrillation within a preset update cycle (a preset time period), or percentage which is occupied by the time duration of the atrial fibrillation within a preset update cycle (a preset time period). In this embodiment, the percentage which is occupied by the time duration of the atrial fibrillation within the preset update cycle is used as the AF Burden. The preset update cycle can be automatically preset by the system, or inputted or modified by the user, and can be measured in minutes, hours, etc. In this embodiment, the update cycle is explained as 1 hour for example. The atrial fibrillation burden display unit 240 displays real-time atrial fibrillation burden on the display interface of the display device, and it can display real-time atrial fibrillation burden in the atrial fibrillation comprehensive view, as shown in the parameter trend area or typical waveform area of
For example, if step 1 acquires the monitoring data during the preset atrial fibrillation monitoring period, the atrial fibrillation analysis unit 220 detects the atrial fibrillation according to the acquired monitoring data to acquire the atrial fibrillation analysis result. In this embodiment, the atrial fibrillation analysis unit 220 detects the atrial fibrillation according to the monitoring data of the electrocortical parameters during the preset atrial fibrillation monitoring period to obtain the atrial fibrillation analysis result. The atrial fibrillation analysis result should at least include information of the atrial fibrillation event that occurs in the patient during the preset atrial fibrillation monitoring period. The specific process is the same as the real-time detection of atrial fibrillation mentioned above, and is not elaborated here.
In some embodiments, the atrial fibrillation analysis unit 220 can also directly acquire the real-time information of the atrial fibrillation event from the monitor through the signal acquisition device 10, or directly acquire the information of the atrial fibrillation event that occurs in the patient during the preset atrial fibrillation monitoring period from the monitor through the signal acquisition device 10.
In step 3, the atrial fibrillation analysis unit 220 displays an atrial fibrillation comprehensive view according to the acquired information of the atrial fibrillation event and the monitoring data of the at least two vital sign parameters. The atrial fibrillation comprehensive view can be automatically displayed or triggered to display under certain conditions. For example, the above content mentioned that when detecting the atrial fibrillation, the atrial fibrillation alarm unit 230 displays the atrial fibrillation alarm information through the display device 30. When the input device 40 receives a click operation of the user on the atrial fibrillation alarm information, the atrial fibrillation analysis unit 220 displays the atrial fibrillation comprehensive view through the display device 30. In other words, when the input device 40 receives the click operation of the user on the atrial fibrillation alarm information, the method proceeds to step 3. It can be seen that after seeing the alarm information of “atrial fibrillation” on the interface shown in
For example, the above content mentions that the atrial fibrillation burden display unit 240 calculates the real-time atrial fibrillation burden according to the preset update cycle, and displays the real-time atrial fibrillation burden information through the display device. When the input device 40 receives the click operation of the user on the real-time atrial fibrillation burden information, the atrial fibrillation analysis unit 220 displays the atrial fibrillation comprehensive view through the display device 30. In other words, when the input device 40 receives the click operation of the user on real-time atrial fibrillation burden information, the method proceeds to step 3. It can be seen that after the doctor sees “AF burden 5%” on the interface shown in
For example, the above content mentioned that the atrial fibrillation analysis unit 220 displays the real-time electrocardiogram waveforms through a display device according to the monitoring data of electrocardiogram parameters. When the input device 40 receives the click operation of the user on the real-time electrocardiogram waveforms, the atrial fibrillation analysis unit 220 displays the atrial fibrillation comprehensive view through the display device 30. In other words, when the input device 40 receives the click operation of the user on the real-time electrocardiogram waveforms, the method proceeds to step 3. It can be seen that after seeing the real-time electrocardiogram waveforms on the interface shown in
Of course, the monitoring system can also preset a hotkey. When the input device 40 receives the click operation of the user on the preset hotkey, the atrial fibrillation analysis unit 220 displays the atrial fibrillation comprehensive view through the display device, the method proceeds to step 3. It can be seen that doctors can see the atrial fibrillation comprehensive view with just one click, which is very convenient.
When the monitoring system monitors multiple patients, the commonly used display interface is shown in
In this embodiment, doctors can use various methods mentioned above to display the atrial fibrillation comprehensive view in the monitoring system, facilitating doctors to quickly master the patient condition.
The atrial fibrillation comprehensive view includes trend graphs 810 of at least two vital sign parameters, a trend graph 820 of the atrial fibrillation event, and an atrial fibrillation burden graph 830. The vital sign parameters displayed in the atrial fibrillation comprehensive view can be preset by the system or the user, such as displaying vital sign parameters, such as heart rate, pulse rate, blood oxygen, non-invasive blood pressure, invasive blood pressure, respiration, body temperature, ST segment information, etc.
In the atrial fibrillation comprehensive view, the trend graph 810 of at least one vital sign parameter and trend graph 820 of the atrial fibrillation event are displayed simultaneously. In this embodiment, how many vital sign parameters are obtained, the trend graphs 810 of as many vital sign parameters as obtained, are corresponding displayed, facilitating the joint presentation of the effect of the occurrence or non-occurrence of the atrial fibrillation event, on at least one vital sign parameter, at any one or more time points or within any one or more time periods during the preset atrial fibrillation monitoring period: as well as facilitating the joint presentation of the effect of the distribution of the atrial fibrillation event, on at least one vital sign parameter, at any one or more time points or within any one or more time periods during the preset atrial fibrillation monitoring period.
By comparing the trends of changes in vital sign parameters and atrial fibrillation events, it can be determined that whether the atrial fibrillation has an effect on the vital sign parameters. For example, from
The trend graph 820 of the atrial fibrillation event and the atrial fibrillation burden graph 830 are displayed simultaneously, so as to jointly present a distribution difference of the atrial fibrillation event within different time periods, which have a designated atrial fibrillation burden value, during the preset atrial fibrillation monitoring period. The designated atrial fibrillation burden value can be of interest to doctor. Comparing the trend graph 820 of the atrial fibrillation event with the atrial fibrillation burden graph 830, different information can be presented. Under the same atrial fibrillation burden, the distribution of atrial fibrillation event at different time periods may vary greatly. For example, when the atrial fibrillation burden are all 50%, by combining the trend graph 820 of the atrial fibrillation event, it can be seen that the distribution and occurrence rule of atrial fibrillation events can be completely different. For example, when the atrial fibrillation burden are both 50%, when observing the trend graph 820 of the atrial fibrillation event, it may be observed that the atrial fibrillation occurs in the first half hour in some time periods, the atrial fibrillation occurs in the last half hour in some time periods, while the atrial fibrillation occurs uniformly in some time periods, etc. The comprehensive presentation of trend graph 820 of the atrial fibrillation event and atrial fibrillation burden graph 830 has clinical significance for medical staff, and is also helpful for doctor to distinguish whether the atrial fibrillation type of patient is paroxysmal, persistent, or permanent.
The trend graph 810 of at least one vital sign parameter and the atrial fibrillation burden graph 830 are displayed simultaneously, which also facilitates the joint presentation of the effect of the magnitude and/or the trend of change of the atrial fibrillation burden over time, on the at least one vital sign parameter, within any one or more time periods during the preset atrial fibrillation monitoring period. By comparing the trends of changes in the vital sign parameters and atrial fibrillation burden, it can be determined whether the atrial fibrillation burden has an effect on the vital sign parameter. For example, the atrial fibrillation burden graph 830 and the trend graph 810 of heart rate are jointly presented. Doctors can observe the effect of atrial fibrillation burden on ventricular rate and whether high heart rate is related to the atrial fibrillation burden. If the correlation is average, doctors can directly prescribe drugs to control ventricular rate. If the correlation is highly and the patient further has a relatively high ventricular rate and obvious symptoms, doctors may adjust the type of medication. In addition to simply controlling ventricular rate, they may also directly perform medication cardioversion, such as using amiodarone drugs to convert atrial fibrillation into sinus rhythm, thereby completely controlling ventricular rate. In addition, doctors may not only prescribe medication, but also make decisions to undergo atrial fibrillation ablation surgery to address the source problem. It can be seen that the joint presentation of the two is beneficial for doctors to make accurate determinations about the patient condition and take further measures.
The trend graphs 810 of at least one vital sign parameter, the trend graph 820 of the atrial fibrillation event and the atrial fibrillation burden graph 830 are displayed simultaneously, so as to jointly present a comprehensive effect of the occurrence and non-occurrence of the atrial fibrillation event and/or the distribution of the atrial fibrillation event, the magnitude and/or the trend of change of the atrial fibrillation burden over time, on the at least one vital sign parameter, during the preset atrial fibrillation monitoring period. For example, ART is arterial blood pressure, that is, a kind of IBP (invasive blood pressure) and a kind of hemodynamic parameter. Through the atrial fibrillation burden graph 830, the trend graph 820 of the atrial fibrillation event, and the trend graph of the arterial blood pressure (ART), doctors can see how much the atrial fibrillation burden or whether atrial fibrillation occurs, and their effect on hemodynamics of the circulatory system.
In this embodiment, the trend graphs 810 of vital sign parameters, the trend graph 820 of the atrial fibrillation event, and the atrial fibrillation burden graph 830 are aligned in time, as shown in
The trend graph 820 of the atrial fibrillation event in
Similarly, the trend graphs 810 of vital sign parameters can also use various elements mentioned above to present the trends of vital sign parameters, and is not further elaborated here. By using various trend graphs, such as trend graphs 810 of vital sign parameters and trend graph 820 of the atrial fibrillation event, it is easy to observe the development trend of variables to be observed (such as atrial fibrillation events, vital sign parameters, etc.) over a predetermined time period.
Specifically, the atrial fibrillation analysis unit 220 marks the occurrence time point of the atrial fibrillation event on the trend graph 820 of the atrial fibrillation event through a preset first marker to distinguish between the occurrence time point of the atrial fibrillation event and the time point when the atrial fibrillation event does not occur. For example, in the embodiment shown in
When the atrial fibrillation analysis unit 220 displays through the display device 30, the trend graph 810 of at least one vital sign parameter (in this embodiment, all vital sign parameters of which the monitoring data is acquired), and the trend graph 820 of the atrial fibrillation event, a preset marker is configured to associate the atrial fibrillation event in the trend graph 820 of the atrial fibrillation event, with the vital sign parameter in the trend graph 810 of at least one vital sign parameter. The preset marker can be in various ways, such as various shapes, patterns, colors, etc., as long as it can highlight the association between the atrial fibrillation event and vital sign parameter. The preset marker shown in
In some embodiments, the atrial fibrillation analysis unit 220 marks a part of the trend graph 810 of at least one vital sign parameter (in this embodiment, all vital sign parameters of which the monitoring data are acquired), which part is at a time point or in a time period, when the atrial fibrillation event occurs. Therefore, when observing the trends of the vital sign parameters, doctors can determine the correlation between the vital sign parameters and the atrial fibrillation events without looking at the trend graph of atrial fibrillation event, which is very convenient. There are various ways to mark, such as using various graphics, patterns, colors, etc., as long as it can highlight the time point or time period when the atrial fibrillation event occurs.
The atrial fibrillation analysis unit 220 also processes the monitoring data of at least two vital sign parameters to identify the extremums of the at least two vital sign parameters and/or their occurrence time points, during the preset atrial fibrillation monitoring period. In this embodiment, when identifying the extremums of various vital sign parameters, the occurrence time points of the extremums are also identified correspondingly. The extremum can be either the maximum value or the minimum value. In this embodiment, the extremum includes the maximum value and the minimum value.
When the atrial fibrillation analysis unit 220 displays the trend graphs 810 of at least two vital sign parameters through the display device, the display device also presents the extremums and/or their occurrence time points of the at least two vital sign parameters. The extremums and/or their occurrence time points can be presented in various ways, such as displaying only the numerical values of the extremums and/or their occurrence time points, or only marking the positions (time points) where the extremums occur on the trend graph. Of course, it is also possible to both display the numerical values of the extremums and/or their occurrence time points, and mark the positions where the extremums occur. In this embodiment, the trend graph 810 of each vital sign parameter shows the maximum value and its occurrence time point, the minimum value and its occurrence time point. There are various ways to present the extremum, such as using various graphics, text, patterns, colors, etc. to mark it. If a time coordinate is set in the atrial fibrillation comprehensive view, marking the extremum is equivalent to marking its occurrence time point. In this embodiment, the extremum accompanied by the atrial fibrillation and the extremum without the atrial fibrillation are displayed differently. For example, the atrial fibrillation analysis unit 220 highlights through a display device the extremum and/or its occurrence time point accompanied by the atrial fibrillation, such as highlighting by color, brightness, etc. For example, the atrial fibrillation analysis unit 220 displays through the display device, the extremum and/or its occurrence time point accompanied by the atrial fibrillation with a preset first marker or text, and the extremum and/or its occurrence time point without the atrial fibrillation with a preset second marker or text. The first and second markers can be various shapes, patterns, etc., as if they can be different. Of course, the better one is that the first marker is more eye-catching than the second marker. The first marker in
The trend graphs 810 of vital sign parameters can be one of a curve graph, a histogram, a bar graph, a box line graph, a scatter graph, a broken line graph, or any combination of the curve graph, histogram, bar graph, box line graph, scatter graph, broken line graph. As shown in
In some embodiments, as shown in
In some embodiments, the vital sign parameters include at least two of: systolic blood pressure, diastolic blood pressure, and mean blood pressure, and their trend graphs also share a vertical coordinate representing the numerical value of the vital sign parameters. In
The atrial fibrillation analysis unit 220 can also distinguish and display on the display device, the trend graphs of vital sign parameters sharing a common vertical axis by using different colors. For example, the heart rate curve E and pulse rate curve F in
The atrial fibrillation comprehensive view further includes at least one of: statistical information for atrial fibrillation, statistical information for vital sign parameter, statistical information for typical event, and typical waveform information, as shown in
The atrial fibrillation analysis unit makes statistics on the monitoring data of vital sign parameter during the preset atrial fibrillation monitoring period, and acquires statistics information for the vital sign parameter. The statistics information for the vital sign parameter includes at least one of the following: extremum of the at least one vital sign parameter and its occurrence time point, average value of the at least one vital sign parameter, and statistical information segmented, of the at least one vital sign parameter.

The atrial fibrillation analysis unit performs statistics on typical events during the preset atrial fibrillation monitoring period, and acquires statistical information for typical event. Statistical information for typical event include at least one of the following: count of rapid ventricular rate in the atrial fibrillation, count of atrial fibrillation with RR long interval(s), count of extreme tachycardia, count of extreme bradycardia, a time point of first-onset atrial fibrillation, a time point of atrial fibrillation with maximum heart rate, and an occurrence time period of the longest atrial fibrillation. Typical events are usually events that doctors focus on and have clinical significance. The atrial fibrillation comprehensive view can also include an alarm event statistical chart during the preset atrial fibrillation monitoring period. The alarm event statistical chart can reflect various alarms generated by the monitoring system during patient monitoring. Of course, it also includes atrial fibrillation alarm events. Alarm events are also typical events, and the alarm event statistical chart can be displayed as a part of the statistical information for typical event in the information statistics area of
The atrial fibrillation analysis unit processes the monitoring data of electrocardiogram signals to obtain typical waveform information. Typical waveform information includes at least one fragment of at least one of the following waveforms: electrocardiogram waveform(s) of first-onset atrial fibrillation of the patient, electrocardiogram waveform(s) containing a highest heart rate during the preset atrial fibrillation monitoring period, electrocardiogram waveform(s) containing a lowest heart rate during the preset atrial fibrillation monitoring period, and electrocardiogram waveform(s) corresponding to atrial fibrillation of longest time duration during the preset atrial fibrillation monitoring period. Typical waveform information can be presented to doctors as typical electrocardiogram waveforms, and has clinical significance.
