1. A system for analyzing and mapping electrophysiological (EP) data from a tissue of a body, the EP data measured by a plurality of sensors disposed along a distal end of a medical device that is positionable near the tissue of the body, the system comprising: an electronic control unit (ECU) configured to: acquire the EP data from the plurality of sensors; determine a position of a sensor from the plurality of sensors; compute a metric based on the EP data from the plurality of sensors; apply a matched filter to one or more of the EP data and values of the metric to identify EP patterns on the tissue of the body; and recognize multiple depolarization wavefront patterns in a cardiac activation from the EP patterns on the tissue of the body.
