Patent ID: 8306612

Claim:
A computer-assisted method for guiding an operator in defining electrode positions upon a display of a segmented heart model, in order to construct a more accurate map than achievable without such guidance, the segmented heart model being included in a map panel on a display screen, comprising the steps of: advancing a catheter into a beating heart, the catheter having a proximal end and a distal end that supports one or more electrodes; obtaining an image during a beat of the heart, the image including one or more darkened portions corresponding to locations of the one or more electrodes; presenting the image in the same map panel that includes the display of the segmented heart model; confirming a current location of the one or more electrodes at the actual position of the catheter relative to the segmented heart model; capturing EP data that represents electrophysiological signals of the beating heart at the current location for each of the one or more electrodes; applying a signal processing algorithm to the captured EP data in view of the confirmed current location of the one or more electrodes to result in a calculation; and mapping the calculation at the confirmed location of the one or more electrodes.
