Catheter Ablation of Idiopathic Left Anterior Fascicular Ventricular Arrhythmias: Predicting Origin Sites via Mapping and Electrocardiography

Idiopathic ventricular arrhythmias (VAs) arising from the left anterior fascicle (LAF) are uncommonly seen, and their characteristics still need to be sufficiently investigated. This study aimed to conclude these VAs' characteristics and explore efficient ablation strategies.
