摘要:

［目的］分析完全性左束支传导阻滞患者的病因及心功能情况。［方法］回顾分析大连医科大学附属第一医院2006年6月~2009年12月收治的65例完全性左束支传导阻滞患者（心电图已明确诊断），采用冠状动脉造影（judkins法）、超声心动图检查（左心室射血分数）及6 min步行试验测量分析心脏功能。［结果］在所有病因中以冠心病最常见占45%，高血压17 % ，扩张性心肌病15% ，风湿性心脏病5%，无器质性心脏病17%。合并器质性心脏病患者的心功能比较差，尤其以冠心病患者最多见，无器质性心脏病患者的心功能正常。［结论］完全性左束支传导阻滞多见于器质性心脏病，也可见于健康人。常见病因为冠心病、其次是高血压，也可见于风心病、心肌病等。完全性左束支传导阻滞伴有胸痛及心电图异常变化的患者，行冠状动脉造影和相关心功能检查对临床治疗有一定的价值。

Abstract:

［Objective］To assess etiology of complete left bundle branch block (LBBB) and cardiac function. ［Methods］Sixty-five inpatients with electrocardiographic findings of LBBB underwent coronary artery angiography (Judkins technique), echocardiography (LVEF) and six minutes walk test to evaluate heart function.［Results］ Of all etiologies, coronary artery disease (CAD) accounted for 45%, hypertension (HP) 17%, dilated cardiomyopathy (DCM) 15%, rheumatic heart disease 5%, and isolated LBBB 17%. Cardiac function of LBBB with organic heart disease was worse, especially CAD, however isolated LBBB was normal. ［Conclusions］ The main of CLBBB was organic heart disease, few was normal. The most etiology of CLBBB was CAD、HP、DCM and rheumatic heart disease. When CLBBB in patients were accompanied by chest pain or electrocardiographic abnormality, coronary artery angiography and other cardiac function techniques were helpful to clinical treatment.
