摘　　要：目的 左束支传导阻滞(LBBB)是一种常见的心脏传导系统病变,可引起左心室重构和功能障碍,诱发心衰,导致不良预后。心脏再同步化治疗(CRT)是其常用的治疗方法,但术后反应存在差异,这可能与LBBB的分型有关,真性左束支传导阻滞(TLBBB)患者更易获益。斑点追踪超声心动图(STE)能够评估心肌机械运动模式的变化,精确评价左室同步性和心功能,在CRT治疗术前有助于筛选候选者,预测CRT反应,术后随访协助评估反应、优化参数设置,具有重要应用价值。Left Bundle Branch block(LBBB)is a common pathology of the cardiac conduction system that can cause left ventricular remodelling and dysfunction,inducing heart failure and leading to a poor prognosis.Cardiac Resynchronization Therapy(CRT)is its treatment,but there are differences in post-procedure response,which may be attributed to the classification of LBBB,and patients with True Left Bundle Branch block(TLBBB)are more likely to benefit from CRT.Speckle Tracking Echocardiography(STE)can assess the changes in myocardial mechanical motion patterns,accurately evaluate left ventricular synchronization and cardiac function,and has important application value in the prediction and follow-up of CRT treatment.
