BACKGROUND Atrioventricular nodal reentry tachycardia (AVNRT) is common in adults and often involves reentry through ≥2 atrioventricular nodal-atrial connections. Although AVNRT can be a trigger for atrial fibrillation (AF), we have observed new-onset AVNRT after AF ablation procedures. OBJECTIVE The purpose of this study was to determine whether ablation involving the septum or proximal coronary sinus (CS) during AF ablation may create a substrate favorable for AVNRT.
