Methods and systems for generating integrated substrate maps for cardiac arrhythmias

A method of generating an electrophysiology map from a plurality of electrophysiology data points, comprising:

• accepting user input selecting a first filtering criterion applicable to a first electrophysiological characteristic, a second filtering criterion applicable to a second electrophysiological characteristic, and a prioritization of the first electrophysiological characteristic and the second electrophysiological characteristic;
• applying the first filtering criterion and the second filtering criterion to the plurality of electrophysiology data points to generate a subset of the plurality of electrophysiology data points;
• and
• outputting a graphical representation of the subset of the plurality of electrophysiology data points, wherein the graphical representation includes a graphical representation of the first electrophysiological characteristic and a graphical representation of the second electrophysiological characteristic, and
• wherein a higher priority electrophysiological characteristic of the first electrophysiological characteristic and the second electrophysiological characteristic is rendered preferentially to and to the exclusion of a lower priority electrophysiological characteristic of the first electrophysiological characteristic and the second electrophysiological characteristic in regions of overlap between the first electrophysiological characteristic and the second electrophysiological characteristic.
