摘要

一名74岁的非缺血性心肌病患者，左室射血分数（LVEF）为20%，左束支传导阻滞（LBBB），在左室口使用LBBP导联成功植入心脏再同步治疗除颤器（CRT-D）。尽管LVEF在6个月时恢复正常，但患者在植入后10个月出现晚期导联脱位和左室功能下降。由于将传导的搏动作为心室颤动感知事件来感知，因此LV捕获管理算法无效。LBBP导联的移除和替换导致左室功能的恢复。

Late dislodgement of left bundle branch pacing lead and failure of left ventricle capture management algorithm

A 74-year-old man with nonischemic cardiomyopathy, LV ejection fraction (LVEF) of 20 % and left bundle branch block (LBBB) underwent successful cardiac resynchronization therapy defibrillator (CRT-D) implantation utilizing LBBP lead in the LV port. Despite normalization of LVEF at 6 months, patient presented with late lead dislodgment at 10 months post-implant and decline in LV function. LV capture management algorithm was inactive due to sensing of conducted beat as ventricular fibrillation sensed event. Removal and replacement of LBBP lead resulted in recovery of LV function.
