SYSTEM AND METHOD FOR DETERMINING REENTRANT VENTRICULAR TACHYCARDIA ISTHMUS LOCATION AND SHAPE FOR CATHETER ABLATION

摘要

A method and system for identifying and localizing a reentrant circuit in a heart of a subject during sinus rhythm is provided. The method may include (a) receiving electrogram signals from the heart during sinus rhythm via electrodes (s151), (b) creating a map based on the electrogram signals (s152), (c) determining, based on the map, a location of the reentrant circuit isthmus in the heart (s153-s155), and (d) displaying the location of the reentrant circuit isthmus (s156).
