1. A method for providing an electroanatomical representation of a patient'"'"'s heart, the method comprising:

  • measuring signals at one or more electrodes 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;

    selecting portions of a first signal to process to determine a triggering event based on a second, different signal of the measured signals;

    applying an algorithm to the selected portions of the first signal to determine the triggering event in the first signal;

    synchronizing, by the computer, the signals measured at the one or more electrodes with one another according to a heartbeat 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.
