目的探讨完全性左束支阻滞(CLBBB)病例的临床特点。方法回顾性分析68例CLBBB住院患者的临床特点和冠状动脉造影资料。结果 68例CLBBB患者中合并冠心病、高血压病和扩张型心肌病者分别占57.8%、49.4%和38.2%。合并心脏扩大或心功能不全者71.2%,合并室性心律失常者78.3%,合并房室阻滞者38.1%。结论 CLBBB绝大多数见于器质性心脏病,尤其是冠心病、高血压病、心肌病等,常伴发心功能不全和各种其他类型心律失常。年龄≥65岁、合并糖尿病和/或高血压病的CLBBB患者容易合并冠心病。
Objective To investigate the clinical features of complete left bundle branch block (CLBBB). Methods The clinical features and coronary angiography data of 68 patients with CLBBB hospitalized were retrospectively analyzed. Results 68 cases of CLBBB patients with coronary heart disease, hypertension and dilated cardiomyopathy accounted for 57.8%, 49.4% and 38.2%. 71.2% of patients with cardiac enlargement or cardiac insufficiency, 78.3% of patients with ventricular arrhythmia, and 38.1% of patients with atrioventricular block. Conclusion The vast majority of CLBBB found in organic heart disease, especially coronary heart disease, hypertension, cardiomyopathy, etc., often accompanied by cardiac insufficiency and a variety of other types of arrhythmias. Patients aged ≥65 years with CLBBB who have diabetes mellitus and / or hypertension are more likely to have coronary heart disease.
