Point of interest (poi) map for cardiac arrhythmia diagnosis

Abstract

A system includes a display and a processor. The processor is configured to receive a cardiac anatomical surface, and to receive multiple electrophysiological (EP) data points comprising (i) respective locations on the cardiac anatomical surface and (ii) respective values of arrhythmia-indicative EP parameters at the locations, and apply respective criteria to the values of the EP data points. For each EP data point whose value meets a respective criterion, the processor is configured to graphically encode the EP data point to generate a point of interest (POI), superimpose POIs of at least two types of arrhythmia-indicative EP parameters on the anatomical surface as to generate a POI map reflecting surface locations likely of being arrhythmogenic, and visualize the POI map to a user, on the display.
