Patent ID: 8428700

Claim:
A method for providing an electroanatomical representation of a patient's heart, the method comprising: measuring signals at one or more electrodes at multiple positions in the patient's heart cavity over a time period including multiple heart beat cycles, at least some of the signals being in response to electrical activity in the patient's heart cavity; applying an algorithm to one or more specific signals of the measured signals to determine a triggering event in the specific signal, with applying the algorithm including: selecting portions of the specific signal to process to determine the triggering event based on a second, different signal of the measured signals by processing the second signal to determine an event corresponding in time to a potential undesired triggering event in the specific signal; and selecting a portion of the specific signal that excludes the time period including the potential false triggering event; synchronizing, by the computer, the signals measured at the one or more electrodes with one another according to a heart beat cycle based on the triggering event; and generating, by the computer, the electroanatomical representation of the patient's heart based on the synchronized measured signals and positions of the catheter electrodes.
