Abstract
A method for determining electrophysiology properties of tissue comprising acquiring electrical signal data from a plurality of electrodes () of one or more catheters, determining at least one electrode clique from the plurality of adjacent electrodes (), computing local conduction velocity vectors for the at least one electrode clique (), determining at least one catheter orientation independent indicator from which to classify an arrhythmia source based on one or more of an angular dependence parameter associated with a flow field of the local velocity conduction vectors, an eccentricity parameter reflecting the uniformity of local conduction velocity, and divergence and curl-like sums or closed path integral parameters associated with the local velocity vectors, and displaying a rhythm classification responsive to catheter movement thereby facilitating identification of types and causes of arrhythmia disorders.
