Clinically Documented but Not Inducible Atrioventricular Nodal Reentrant Tachycardia: To Ablate or Not To Ablate?

Conference paper

Abstract

Several studies have shown that most sustained supraventricular tachycardia can be induced during electrophysiological studies. However, some documented tachyarrhythmias could not be induced during such studies despite infusion of isoproterenol and atropine [1–10]. It is important to study the electrophysiological mechanisms and characteristics of these patients, because the correct diagnosis and target site selected for ablation may be overlooked.
