His Resynchronization Versus Biventricular Pacing in Patients With Heart Failure and Left Bundle Branch Block.

ABSTRACT:

Background

His bundle pacing is a new method for delivering cardiac resynchronization therapy (CRT).

Objectives

The authors performed a head-to-head, high-precision, acute crossover comparison between His bundle pacing and conventional biventricular CRT, measuring effects on ventricular activation and acute hemodynamic function.

Methods

Patients with heart failure and left bundle branch block referred for conventional biventricular CRT were recruited. Using noninvasive epicardial electrocardiographic imaging, the authors identified patients in whom His bundle pacing shortened left ventricular activation time. In these patients, the authors compared the hemodynamic effects of His bundle pacing against biventricular pacing using a high-multiple repeated alternation prot
