Claims
- 1. A device-implemented software system operating to monitor, control and adjust a detection window comprising:
means for checking evidence of tachyarrhythmias; means for computing values between TLRI and DVAI; means for setting PAV based on results obtained from said means for computing values; and means for setting the TLRI equal to a sum of the DVAI and PAV; said means for checking, said means for setting PAV and said means for setting the TLRI being in operable logic control of said software system.
- 2. The software system of clam 1 wherein said means for checking tachyarrhythmias includes means for entering a ventricular event.
- 3. The software system of claim 1 wherein said means for computing values includes means for calculating the difference between the TLRI and the DVAI.
- 4. The software system of claim 1 wherein said means for setting PAV includes means for reviewing said difference between the TLRI and the DVAI and comparing the difference value with the PAV.
- 5. The software system of claim 1 wherein said means for setting the TLRI includes means for taking a sum of DVAI and PAV.
- 6. A method of adjusting PAV to minimize the input of atrial pacing in a detected tachyarrhythmias episode, the method comprising:
monitoring evidence of possible tachyarrhythmia; comparing the difference between TLRI and DVAI with PAV if evidence of possible tachyarrhythmias is confirmed; comparing the difference between TLRI and DVAI with minimum PAV if the difference between TLRI and DVAI is less than PAV; setting PAV to the minimum PAV if the difference between TLRI and DVAI is less than the minimum PAV; and setting the TLRI equal to the sum of DVAI and PAV.
- 7. The method of claim 6 wherein the method of comparing the difference between TLRI and DVAI with PAV includes indicating no change to PAV or TLRI if the difference is greater than or equal to PAV.
- 8. The method of claim 6 wherein the method of comparing the difference between TLRI and DVAI with minimum PAV includes setting PAV equal to the difference between TLRI and DVAI if that difference is greater or equal to minimum PAV.
- 9. The method of claim 6 wherein said method of setting the TLRI equal to the sum of DVAI and PAV is subsequent to setting PAV equal to minimum PAV.
