Abstract
Right ventricular pacing (RVP) is conventionally preferred in the treatment of patients with atrioventricular block. However, long-term RVP may lead to pacing-induced cardiomyopathy (PICM), characterized by new-onset or worsening ventricular functions due to dyssynchronous ventricular electrical activation, abnormal ventricular remodeling, and increased energy expenditure. Historically, biventricular pacing (BVP) and guideline-directed medical therapy were the only treatment option for PICM. Recently, conduction system pacing, including left bundle branch area pacing (LBBaP), has emerged as a physiological alternative to BVP, showing better results in electro-mechanical ventricular synchronization and hemodynamic parameters compared to BVP. We present a case involving a patient from whom the PICM was successfully recovered shortly after LBBaP.
