Recurrent supraventricular tachycardias prevalence and pathophysiology after RF ablation: A 5-year registry

Abstract

Although electrophysiological study and RF ablation eliminated different types of SVT. However, there may be increased incidence of recurrence among pts with AVNRT and AVRT utilizing concealed septal AP and multiple APs secondary to the complexity of AVN physiology, the critical location of septal AP, the clinical expertise, and poor electrophysiological criteria for good procedural success.
