Radiofrequency ablation of slow pathway in patients with atrioventricular nodal reentrant tachycardia. Do arrhythmia recurrences correlate with persistent slow pathway conduction or site of successful ablation? (original) (raw)

Residual slow pathway conduction is often observed post radiofrequency (RF) ablation in patients with atrioventricular nodal reentrant tachycardia (AVNRT). This study evaluated whether arrhythmia recurrences after RF ablation correlate with persistent slow pathway conduction or the site of successful ablation. Among 55 patients assessed, those with posterior ablation sites experienced higher recurrence rates compared to those with anterior sites, while no significant correlation with persistent conduction was found.
