摘要：
A method is provided for identifying an isthmus in a three-dimensional map of a cardiac cavity by means of a processing unit configured to perform the following steps: a) correlation between a set of stimulated points of the cardiac cavity, each stimulated point being represented by a set of signals that are obtained following surface electrocardiography (ECG), excluding ventricular tachycardia； b) identification of a watershed line on the basis of the above correlation results and of the 3D coordinates of the stimulated points in the 3D map； and c) determination of the isthmus based on a 3D corridor substantially transverse to the watershed line.
