完全性左束支传导阻滞(CLBBB)是一种较不常见却有重要临床意义的心电图异常。近年来关于其病因、预后均有不同看法。特别是CLBBB合并电轴左偏(LAD)的问题更有所争论。鉴于国内有关报导甚少,本文就我院十年中31例CLBBB病人的病因、临床表现、心电图表现以及预后进行比较分析,以了解CLBBB的远期预后并对合并LAD的临床意义进行探讨。资料与方法 (一)诊断标准:1.QRS间期≥0.12秒;2.左室面导联有宽大、粗钝的R波,一般没有q波;V_1～V_3导联呈QS型,r波没有或很小;3.ST—T与QRS主波方向相反;4.排除预激综合征和室性心律。 (二)随访对象:为1976年1月至1986
Complete left bundle branch block (CLBBB) is a less common but clinically significant ECG abnormality. In recent years about its etiology, prognosis have different views. In particular, the issue of CLBBB with LAD left even more controversial. In view of the few reports in our country, this essay compares the etiology, clinical manifestation, electrocardiogram and prognosis of 31 CLBBB patients in our hospital in ten years to understand the long-term prognosis of CLBBB and to discuss the clinical significance of the combined LAD. Materials and methods (a) diagnostic criteria: 1.QRS interval ≥ 0.12 seconds; 2 left ventricular lead with large, blunt R wave, generally without q wave; V_1 ~ V_3 lead was QS type, r wave No or very small; 3.ST-T and QRS main wave opposite; 4. Exclusion of WPW and ventricular rhythm. (B) follow-up target: January 1976 to 1986
