Abstract
Conduction system pacing has emerged as a new pacing technique to achieve cardiac physiologic pacing, but its utility and safety in patients with atrial fibrillation undergoing simultaneous ablation of the atrioventricular node remains seemingly unknown. Here, we present a case series of 10 patients with long-standing persistent or permanent atrial fibrillation who failed rate-control therapy and elected to proceed with simultaneous ablation of the atrioventricular node and His-bundle pacemaker implantation.
