REVERSAL OF PACEMAKER-INDUCED CARDIOMYOPATHY AFTER CONDUCTION SYSTEMPACING – LEFT BUNDLE STIMULATION

Abstract

Right ventricular endomyocardial stimulation is associated with the risk of developing pacemaker-induced cardiomyopathy in patients with a high pacing percentage. According to current European guidelines, possible treatment options include upgrading to a cardiac resynchronization system or His bundle pacing. We present a patient with pacemaker-induced cardiomyopathy, in whom after implantation of a left bundle branch pacing lead, conduction system pacing was achieved. Follow-up revealed improvement in left ventricular systolic function and reversal of symptoms.
