AUTOMATED PACE-MAPPING FOR IDENTIFICATION OF CARDIAC ARRHYTHMIC CONDUCTIVE PATHWAYS AND FOCI

摘要

Ventricular tachycardia signals are induced in a liv-ing subject. Pace-mapped signals are then obtained from multiple points within the ventricle, and automatically compared numerically with the induced signals. Recogni-tion of a high degree of cross correlation between the induced signals and one or more of the pace-mapped sig-nals identifies arrhythmogenic foci or pathways, which may then be ablated, so that the the arrhythmia becomes non-inducible.
