自1967年以来,左前分支阻滞(LAH)的诊断已普遍在临床上应用,但是心电图(ECG)和心向量图(VCG)的定量诊断标准尚不一致。本文就155例电轴左偏的ECG和VCG进行分析。材料和方法本文为1978～1981年的VCG连号资料2220份,同时皆附有常规12导联ECG记录。从中检出电轴左偏(0°～-90°)的病例,并对伴有左室肥厚、左束支阻滞、右束支阻滞、心肌梗塞、预激综合征等能够影响电轴偏左的病例除外后共155例。年龄8～87岁,男性138例,女性27例。将155例ECG按
Since 1967, the diagnosis of left anterior branch block (LAH) has generally been clinically useful, but the quantitative diagnostic criteria for electrocardiogram (ECG) and cardiogram (VCG) are not consistent. In this paper, 155 cases of axial left ECG and VCG were analyzed. Materials and Methods This article is from 1978 to 1981 VCG serial number data 2220, accompanied by conventional 12-lead ECG records. From left to right axis (0 ° ~ -90 °) cases, and associated with left ventricular hypertrophy, left bundle branch block, right bundle branch block, myocardial infarction, pre-excitation syndrome can affect the electrical axis A total of 155 cases of left-sided cases. Aged 8 to 87 years old, 138 males and 27 females. 155 cases of ECG press
