Claims42
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.
