Systems and methods for clustering wavefront signals in electrophysiological maps

A system for clustering wavefront signals in an electrophysiological map of a cardiac tissue, comprising:

• a processor comprising a memory configured to:
• receive an electrophysiological map of the cardiac tissue displaying propagation of the wavefront signals as a plurality of velocity vectors;
• discretize the received electrophysiological map into a plurality of sections;
• cluster the velocity vectors into at least one group within each section based on predefined criteria;
• and
• generate a trend line representative of each group of clustered velocity vectors within each section in the electrophysiological map.

A non-transitory computer readable recording medium storing program instructions for clustering wavefront signals in an electrophysiological map of a cardiac tissue by causing a computer to execute the steps of:

• receiving an electrophysiological map of the cardiac tissue
• displaying propagation of the wavefront signals as a plurality of velocity vectors;
• discretizing the received electrophysiological map into a plurality of sections;
• clustering the velocity vectors into at least one group within each section based on predefined criteria;
• generating a trend line representative of each group of clustered velocity vectors within each section in the electrophysiological map;
• and
• displaying the trend lines in the electrophysiological map on a display.
