摘　　要：Cardiac resynchronization therapy(CRT)is an evidence-based effective therapy of symptomatic heart failure with reduced ejection fraction refractory to optimal medical ther-apy and associated with intraventricular conduction disturbance,that results in a significant electrical ventricular dyssynchrony.However,the non-response rate to CRT is still 20%−40%.[1]The potential underlying causes of CRT nonresponse are:(1)suboptimal localization of the left ventricular(LV)electrode,far away from the latest activated LV region.
