Abstract: 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.

Abstract: At least some embodiments of the present disclosure is directed to a method of processing cardiac information. The method includes the steps of: receiving an activation waveform comprising a set of activation waveform data; receiving a range of window size. For each of the plurality of window sizes, the method further includes the steps of: selecting a position of a central window; calculating a set of backward correlations; calculating a set of forward correlations; determining a backward confidence value based on the set of backward correlations; and determining a forward confidence value based on the set of forward correlations. Additionally, the method includes the steps of: comparing the set of confidence values to select a designated confidence value and a selected window size corresponding to the designated confidence value; and determining a local cycle length based on the selected window size.
