Abstract:IntroductionRight ventricular (RV) pacing sometimes causes left ventricular (LV) systolic dysfunction, also known as pacing‐induced cardiomyopathy (PICM). However, the association between specifically paced QRS morphology and PICM development has not been elucidated. This study aimed to investigate the association between paced QRS mimicking a complete left bundle branch block (CLBBB) and PICM development.MethodsWe retrospectively screened 2009 patients who underwent pacemaker implantation from 2010 to 2020 in… Show more
