Abstract:
1. A method for determining optimal spatial resolution for mapping cardiac fibrillation in a patient, comprising: obtaining one or more initial electrograms, each electrogram having an initial spatial resolution; calculating at least one electrogram frequency for each initial electrogram; obtaining one or more subsequent electrograms, each subsequent electrogram having a higher spatial resolution as compared to the initial spatial resolution; calculating at least one electrogram frequency for each subsequent electrogram; comparing the at least one subsequent electrogram frequency for each subsequent electrogram with the at least one electrogram frequency for each initial electrogram; and iterating the steps of obtaining one or more subsequent electrograms, each subsequent electrogram having a higher spatial resolution as compared to one or more preceding electrograms, calculating at least one electrogram frequency for each subsequent electrogram, and comparing the at least one electrogram frequency for each subsequent electrogram with at least one electrogram frequency for each preceding electrogram until at least one of a minimum spatial resolution threshold and an optimal spatial resolution is identified for one or more locations in the patient's heart based on the step of comparing.
