摘　　要：目的分析完全性左束支阻滞(CLBBB)病例的临床特点。方法回顾性分析81例完全性左束支阻滞患者的病因、动态心电图、超声心动图、冠状动脉造影结果。结果60岁以上男性43例,占53%。病因以冠心病、高血压、心功能不全多见。本组冠脉造影的28例完全性左束支阻滞患者中确诊为冠心病者16例,占57.14%。超声心动图结果:55%患者心房、心室增大或心房心室同时增大。左室射血分数(LVEF)<50%者22例,占33.8%。动态心电图检查可见左束支阻滞常合并各种类型心律失常。结论完全性左束支阻滞常发生在老年男性患者,常见于器质性心脏病,尤其是冠心病、高血压、扩张型心肌病。完全性左束支阻滞可导致不良的心脏血流动力学效应,导致左心室功能受损。Objective To analyze the characteristics in patients with complete left bundle branch block （CLBBB）. Methods The data of etiology, Halter, Uhracardiograrn and coronary angiograph） of Eighty one patients with CLBBB were retrospectively analyzed. Results There were 43 （53%） patients who were male and more than 60 years old. 28/60 patients （57%） who had underwent CAG were found to have coronary artery, disease. In patients who had UCG, 16 patients had left ventricular hypertrophy, 28 had left ventricular enlargement, 22 patients whose, left ventricular ejection were less than 50%. Conclusion Most patients with CLBBB had coronary artery disease, and had left ventricular anatomy and function injuried. The prognosis of the patients with CLBBB and heart disease was worse than patients without heart disease.
