Abstract
Pacing induced cardiomyopathy is a known complication of high percent right ventricular (RV) pacing. When treated with cardiac resynchronization therapy (CRT), most patients experience recovery of Left Ventricular (LV) systolic function.A small percentage of patients do not respond due to a number of factors.This case examines the management of a 30-year-old patient with pacing induced cardiomyopathy who was found to be a CRT non responder despite optimalLV lead position and whose LV Ejection Fraction normalized followingRV lead revision.
摘要
起搏诱导性心肌病是右心室（RV）高比例起搏的一种已知并发症。接受心脏再同步治疗（CRT）时，大多数患者的左心室（LV）收缩功能会恢复。一小部分患者由于多种因素无反应。本病例探讨了一名30岁起搏诱导性心肌病患者的治疗情况，该患者尽管左心室导线位置最佳，但对CRT无反应，在右心室导线修订后左心室射血分数恢复正常。
