Catheter ablation of right-sided para-Hisian ventricular arrhythmias using a simple pacing strategy

Background Ablation of para-Hisian ventricular arrhythmias (PH-VAs) is challenging because of the close relationship of the origin site and His bundle. Using pacing techniques to differentiate the near-field from far-field His activations, thereby avoiding atrioventricular block, has been reported in patients with para-Hisian accessory pathways. Objectives We applied the same pacing technique and 3-dimensional mapping to guide radiofrequency...
