Abstract
A method includes receiving an anatomical map of at least a portion of a heart. Positions and respective bipolar intracardiac electrogram (EGM) signals measured at the positions are received for at least a region of the anatomical map. Primary activations and secondary activations are identified in the bipolar intracardiac EGM signals. A surface representation of the bipolar intracardiac EGM signals over the region is derived, including the identified primary activations and secondary activations. The surface representation is presented overlaid on the anatomical map.
