Multiple focal atrial tachycardias in a healthy adult population: Characterization and description of successful radiofrequency ablation

Abstract

Background: The electrophysiologic (EP) characteristics and ablation outcomes of focal atrial tachycardia (AT) have been extensively characterized over recent years. However, there are limited published data describing patients who at EP study have more than one sustained focal tachycardia. Objective: To characterize the demographics, tachycardia data, and outcome of patients with successful ablation of more than one focal AT. Methods: A retrospective review of our supraventricular tachycardia database from 2000 to 2006 identified 258 patients who had undergone radiofrequency ablation of focal AT. Ten patients were identified who had more than one sustained focal tachycardia at EP study, inc..
