原发性扩张型心肌病的心电图特点分析

Analysis of Electrocardiogram Character in Primary Dilatation Cardiomyopathy

本文对72例原发性扩张型心肌病患者的心电图进行了分析,心电图异常率100%。其中T波异常最为常见,其次为传导阻滞、异位心律。在T波异常中,T波倒置47例,占本组病人的65.3%。T波倒置类似心肌梗塞的定位改变。故提出,心电图如果出现T波倒置且有定位改变,同时伴有传导阻滞、异位心律,对原发性扩张型心肌病的诊断有一定价值。

The article analysed the electrocardiogram of 72 cases with primary dilatation cardiomyopathy. The abnormal incidence of electrocardiogram was 100% of them, the abnormal T wave was most common, the conduction block and ectopic rhythm were secondary. Of the abnormal T waves T wave inversion was 65.3% (47 cases) in this group, 77.1% in the abnormal T wave. The inversion of T wave was similar to the Position fixed by myocardial infarction, it mostly occurred on leads of Ⅱ, Ⅲ, avF (inferior wall) and secondary occurred on leads of Ⅰ, avL (high lateral wall). It was suggested that if electrocardiogram appeared in the inversion of T wave, moreover it had the change of fixed position with conduction block (especially exist with many kinds of block), ectopic rhythm, it gave a useful clue to diagnose the primary dilatation cardiomyopathy.
