Long‐Term Follow‐Up of Radiofrequency Slow Pathway Ablation for Atrioventricular Nodal Re‐Entrant Tachycardia: Late Outcomes

We report what we believe to be the largest single centre experience, with the longest follow-up for slow pathway ablation, for AVNRT. We observed a low rate of late atrioventricular block that was not clearly higher than the spontaneous rate of heart block, yet still achieving good rhythm control. We believe our data supports radiofrequency slow pathway modification as effective and safe therapy for atrioventricular nodal re-entrant tachycardia.
