Beneficial effects of upgrading to His bundle pacing in chronically paced patients with left ventricular ejection fraction <50%

In paced patients with clinically symptomatic heart failure and LVEF <50%, pHBP upgrade was feasible in 88.9%, with improved left ventricular function and remodeling. Hence, pHBP can be an alternative for patients with pacing-induced cardiomyopathy and CRT nonresponders.
