Comparison of left bundle branch area pacing between patients with pacing-induced cardiomyopathy and non-ischemic dilated cardiomyopathy.

Left bundle branch area pacing (LBBAP) seems to be an alternative to coronary sinus pacing in patients with non-ischaemic dilated cardiomyopathy (NI-DCM) with left bundle branch block (LBBB) and in pacing-induced cardiomyopathy (PICM). The aim of the study was to compare the response of LBBAP in severe forms of both entities.
