Abstract

Systems and methods for identifying potential ablation sites using electrical parameter data are provided. A method includes geometrically isolating an arrhythmogenic substrate in a three-dimensional geometry. The method further includes generating a first cumulative map from a first dataset including electrical parameter data for each vertex in the isolated arrhythmogenic substrate, and generating a second cumulative map from a second dataset including additional data for each vertex. The method further includes generating a third cumulative map from the first and second cumulative maps, and displaying the third cumulative map on the three-dimensional geometry to facilitate identifying potential ablation sites.
