起搏诱导性心肌病临床研究进展

起搏诱导性心肌病通常定义为长期右心室起搏出现左室射血分数的下降.然而最近的研究数据表明,仅依据左室射血分数下降来定义起搏诱导性心肌病可能低估了长期右心室起搏有害影响的发生率,当出现起搏诱导性心肌病时,主要的治疗方式为升级成心脏再同步化治疗,而最新的数据表明,传导系统起搏可能在预防和治疗起搏诱导性心肌病方面有一定优势.现...

Clinical Research on Pacing-Induced Cardiomyopathy

Pacing-induced cardiomyopathy(PICM) is most commonly defined as a drop in left ventricular ejection fraction in the setting of chronic, high burden right ventricular pacing.However, recent data suggest that defining PICM solely on the basis of reduced left ventricular ejection fraction may underestimate the incidence of long-term harmful effects of right ventricular pacing.When PICM occurs, the primary treatment is upgrading to cardiac resynchronization therapy, and the latest data suggest that conduction system pacing may have some advantages in the prevention and treatment of pacemaker-induced cardiomyopathy.This article reviews the research progress of PICM.
