Catheter ablation of ventricular arrhythmias arising from the basal septum of the right ventricle: characteristics and significance of junctional rhythm appearing during ablation

摘要

Background Most right ventricular arrhythmias (VA) originate from the outflow tract. Experiences of VA arising from the basal septum of the right ventricle (RV) are limited. We aimed to describe the ablation procedure and results, focusing on the characteristics and clinical significance of junctional rhythm (JR) appearing during radiofrequency application.
