Abstract: At least some aspects of the present disclosure is directed to a system for processing cardiac information. The system comprises a processing unit configured to: receive an activation waveform comprising a set of activation waveform data of a plurality of signal sections collected at a plurality of locations; receive a range of window size. The processing unit is further configured to: for each signal section of the plurality of signal sections, determine a set of confidence values, each confidence value corresponding to a window size, by iterating through a plurality of window sizes in the range of window size. The processing unit is further configured to determine one of a plurality of local cycle lengths for the each of the plurality of signal sections based on the selected window size and generate a local cycle length histogram based on the plurality of local cycle lengths.

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.
