Sinus Node Injury as a Result of Superior Vena Cava Isolation during Catheter Ablation for Atrial Fibrillation and Atrial Flutter

Abstract

Sinus node may be damaged due to the ablation sites closer to sinus node. The definition of the junction of right atrium and SVC is very important, the ablation sites of anterolateral free wall of the SVC should not be too close to the SVC orifice.
