Abstract

Wenckebach phenomenon is a well-known electrophysiological character of the atrioventricular node (AVN). AVN-pacing during permanent pacemaker implantation is rare. We herein report the first case of Wenckebach phenomenon in a heart failure patient with chronic atrial fibrillation for more than 30 years during the His-bundle pacing (HBP) procedure. The patient’s symptoms improved significantly. AVN-pacing is available, and HBP is helpful for cardiac remodeling and clinical outcomes.
