Abstract

Abstract: Left bundle branch block (LBBB) can result in significant dyssynchrony in left ventricular (LV) contraction, ultimately leading to cardiac remodeling. LBBB can be rate dependent and may appear with LV systolic dysfunction. Cardiac resynchronization therapy (CRT) has been demonstrated to improve hemodynamics as well as clinical symptoms in patients with LBBB. We describe the case of a 57‐year‐old man who underwent CRT implantation due to exertional dyspnea, rate‐dependent LBBB, and impaired left LV systolic function.
