Systems and methods for facilitating display of cardiac information based on sensed electrical signals include a processing unit configured to receive a set of electrical signals; receive an indication of a measurement location corresponding to each electrical signal of the set of electrical signals; and generate an activation histogram corresponding to the set of electrical signals. Systems and methods disclosed herein may be configured to automatically identify activation histograms exhibiting split characteristics, and to facilitate presentation, on a display device, of a cardiac map including highlighted regions corresponding to the identified activation histograms.
