Electrophysiological Characteristics of Focal Atrial Tachycardia Surrounding the Aortic Coronary Cusps

Abstract

ATs surrounding the aortic coronary cusps can be safely and effectively ablated, with good long-term outcomes. In addition to the P-wave morphological features, the A/V ratio of the local electrogram recording during tachycardia facilitated the localization of successful sites.
