Systems and methods for identifying split activation histograms in cardiac mapping procedures

A system for facilitating display of cardiac information, the system comprising:

• a display device configured to present an electroanatomical map of a cardiac chamber based on sensed cardiac electrical signals acquired by a catheter disposed within the cardiac chamber;
• and
• a processing unit configured to:
• receive a plurality of sets of the sensed cardiac electrical signals;
• for each of the plurality of sets of the sensed cardiac electrical signals, receive an indication of a measurement location corresponding to each cardiac electrical signal;
• generate an activation histogram corresponding to each of the sets of the sensed cardiac electrical signals;
• compute a split metric for each activation histogram, wherein the split metric being a value between zero (0) and one (1) so as to provide an indication of a degree to which the activation histogram includes two peaks separated by a trough within a single cycle by at least:
• identifying the two peaks in the activation histogram;
• determining an amplitude of the trough separating the two peaks;
• and
• determining the split metric based at least in part upon the amplitude of the trough;
• and
• facilitate presentation, on the display device, of a highlighted region within the electroanatomical map based on the computed split metric for each activation histogram.
