中文摘要: 左束支传导阻滞(LBBB) 是心力衰竭发生的重要病因,LBBB发生时左心室激动顺序发生改变,引起心脏收缩模式改变,导致心脏电机械不同步,最终导致心力衰竭。目前关于真性LBBB的诊断无统一标准,流行病学特点尚不清晰,本文将着重对LBBB解剖特征、心电图表现、流行病学、病因、临床意义及治疗方式进行论述。
Abstract:Left bundle branch block (LBBB) is an important cause of heart failure. When LBBB occurs, the excitation sequence of the left ventricle changes, leading to the change of cardiac systolic pattern, resulting in cardiac electromechanical asynchronism, and eventually heart failure. At present, there is no unified standard for the diagnosis of true LBBB, and the epidemiological characteristics are unclear. This paper will focus on a comprehensive discussion of LBBB's anatomic features, electrocardiographic manifestations, epidemiology, etiology, clinical significance and treatment.
