ELECTROPHYSIOLOGY SYSTEM AND METHOD FOR IDENTIFYING SIGNIFICANT ELECTROGRAMS

At least some embodiments of the present disclosure is directed to a system for processing cardiac information. The system including a processing unit is configured to: receive a plurality of cardiac electrical signals collected from a plurality of electrodes disposed within a cardiac chamber, wherein the plurality of cardiac electrical signals are acquired over a cardiac beat having a cycle length; and calculate an importance metric for each of the plurality of the cardiac electrical signals, wherein the importance metric represents a contribution of a respective cardiac electrical signal to an overall duty cycle of the cardiac beat as a function of the cycle length.
