Claims
- 1. A method to collect and present cardiac medical information to a physician comprising:
applying at set surface patch electrodes to said patient; positioning an intracavitary electrode on a catheter placed in the heart of said patient; injecting current between pairs of said surface patch electrodes, defining driven electrode axes; measuring the voltage present on intracavitary electrode due to the applied currents; resolving the location of the intracavitary electrode along each of the axes based upon the measured voltage on the intracavitary electrode; collecting multiple intracavitary electrode positions; selecting the exterior most locations and creating a shell based upon the locations of the data set generating a surface geometry; presenting the surface geometry as an image to the physician.
- 2. The method of claim 1 further comprising the steps of:
measuring voltage on the intracavitary electrode generated by the heart creating EP data; projecting the EP data on the surface geometry; displaying the location of said intra-cardiac electrode on said image.
- 3. The method of claim 1 wherein:
said EP data includes the peak to peak value of the voltage measurement.
- 4. The method of claim 3 wherein:
said EP data includes a time value related to relative timing of the measurement voltage and a pre-selected fiducial time.
