Patients with hypertrophic cardiomyopathy (HCM) enter the terminal stage when developed left ventricle enlargement and ejection fraction (EF) reduction. The concomitant complete left bundle branch block (LBBB) is considered an important factor related to poor outcome. Previous research suggested that biventricular pacing has limited effects on such patients. We report a case with end-stage hypertrophic cardiomyopathy who had a miraculous recovery after receiving successful left bundle branch pacing (LBBP).
肥厚型心肌病（HCM）患者出现左心室扩大和射血分数（EF）降低时进入终末期。合并的完全性左束支传导阻滞（LBBB）被认为是与不良预后相关的重要因素。既往研究表明双心室起搏对此类患者效果有限。我们报告1例终末期肥厚型心肌病患者，在成功接受左束支起搏（LBBP）后奇迹般康复。
