Pacing-induced cardiomyopathy in chronic right ventricular apical pacing: a midterm follow-up study.

Background: Data concerning the effect of chronic right ventricular pacing in patients with normal left ventricular ejection fraction (LVEF%) are contradictory. The aim of this study is to evaluate the prevalence of pacing-induced cardiomyopathy (PICM) at midterm follow-up after permanent pacemaker implantation (PPM).

Methods: A series of 170 patients were submitted to PPM within our facility.
