| 摘要 |
The invention relates to a method 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, c) determination of the isthmus based on a 3D corridor substantially transverse to the watershed line. |
