Suppression of Atrial Fibrillation Following Successful Ablation of Atrioventricular Nodal Reentrant Tachycardia: A Case Report

Inducible atrioventricular nodal reentrant tachycardia was demonstrated by electrophysiological studies in a 55-year-old female who suffered from intermittent palpitation, in which paroxysmal atrial fibrillation (AF) was consistently documented by electrocardiogram recordings. After ablation of the slow pathway, the atrioventricular nodal reentrant tachycardia and AF were not inducible. During 2 years of follow-up, there were no recurrences of AF in terms of symptoms or findings from Holter electrocardiograms. We suggest that the AF was triggered by the atrioventricular nodal reentrant tachycardia and the successful ablation of atrioventricular nodal reentrant tachycardia was associated with freedom arising from ablation of AF.
