Abstract:
1. A method of identifying driver sites for cardiac arrhythmias, comprising: acquiring a plurality of electrograms reflecting electrical activity occurring on at least a portion of a patient's heart; generating at least one electrical activity map from the plurality of electrograms, wherein the at least one electrical activity map represents at least one electrogram morphological characteristic; displaying a graphical representation of the at least one electrical activity map using a first display convention to depict the at least one electrogram morphological characteristic represented in the at least one electrical activity map; analyzing, using at least one processor, the at least one electrical activity map to identify at least one site for application of pacing on the at least a portion of the patient's heart, wherein the at least one electrogram morphological characteristic at the identified at least one site for application of pacing is indicative of driver activity; and annotating a location of the identified at least one site for application of pacing on the graphical representation of the at least one electrical activity map using a second display convention, wherein the at least one electrogram morphological characteristic at the identified at least one site for application of pacing comprises regular electrogram activity, and wherein the regular electrogram activity comprises a constant electrogram cycle length and a constant electrogram morphology.
