从1992年以来,我们采用尹氏HC导联心电轴测量法对11例左前分支阻滞(LAH)的病例进行常规导联与HC导联对照研究,以寻找HC导联诊断LAH诊断标准.现报道如下.资料和方法 选择典型LAH11例,临床和常规导联心电图均十分典型,电轴—40°——73°,不合并其他束支阻滞等异常情况.计男8例,女3例,年龄20—84(平均60)岁.原发病:高血压病Ⅱ期3例、冠心病1例、慢性肾衰尿毒症1例、先天性心脏病1例、其他5例.临床包括x线胸片、心脏超声波等检查与常规导联心
Since 1992, we use Yin’s HC lead axis measurement in 11 cases of left anterior branch block (LAH) cases of conventional lead and HC lead control study to find HC lead diagnosis of LAH diagnostic criteria. Are reported as follows.Data and methods to select a typical LAH11 cases, clinical and routine lead ECG are typical, the electric axis -40 ° --73 °, does not merge with other bundle branch block and other abnormalities .Total male 8, female 3 Cases, age 20-84 (average 60) years old.The primary disease: hypertensive disease in 3 cases, coronary heart disease in 1 case, chronic renal failure uremia in 1 case, congenital heart disease in 1 case, the other 5 cases .Clinical include x-ray, heart ultrasound and other tests with the conventional lead heart
