Methods and Systems for Generating Integrated Substrate Maps for Cardiac Arrhythmias

A method of generating an electrophysiology map, comprising:

• acquiring geometry information pertaining to an anatomical region, the geometry information comprising position information for a plurality of points in the anatomical region;
• acquiring electrophysiology information pertaining to the anatomical region, the electrophysiology information comprising a plurality of electrophysiological characteristics of the anatomical region;
• associating the geometry information with the electrophysiology information as a plurality of electrophysiology (“EP”) data points;
• accepting user input to select a first electrophysiological characteristic of the plurality of electrophysiological characteristics, a first filtering criterion for the first electrophysiological characteristic, and a first priority for the first electrophysiological characteristic;
• applying the first filtering criterion to the plurality of EP data points to output a first subset of the plurality of EP data points satisfying the first filtering criterion;
• accepting user input to select a second electrophysiological characteristic of the plurality of electrophysiological characteristics, a second filtering criterion for the second electrophysiological characteristic, and a second priority for the second electrophysiological characteristic;
• applying the second filtering criterion to the plurality of EP data points to output a second subset of the plurality of EP data points satisfying the second filtering criterion;
• outputting a three-dimensional graphical representation of the first and second subsets of the plurality of EP data points according to the first priority and the second priority.

A system for generating an electrophysiology map, comprising:

• an electrophysiology data point processor configured to accept as input geometry information and electrophysiology information pertaining to an anatomical region and to associate the geometry information with the electrophysiology information as a plurality of electrophysiology data points;
• a filtering processor configured to accept as input a user's selection of n electrophysiological characteristics, wherein each of the n selected electrophysiological characteristics has an associated filtering criterion and an associated priority, and to apply the filtering criteria to their respective ones of the n selected electrophysiological characteristics;
• and
• a mapping processor configured to output a three-dimensional representation of the filtered n selected electrophysiological characteristics according to their respective priorities.
