Reversal of left bundle branch block–induced cardiomyopathy by His bundle pacing
Journal of International Medical Research, 2020 A 61-year-old woman was referred to our institution for evaluation of severe nonischemic dilated cardiomyopathy and left bundle branch block (LBBB). After permanent His bundle pacing, the LBBB was immediately corrected; however, the right bundle branch ...
