急性心肌梗塞时的心电图变化有无预后意义,目前意见不一。作者在本文中指出一种心电图征象—M复合波的出现常伴有各种并发症,为预后不良的指示。所谓M复合波是指呈单相波形的qRST波。(摘者注:指qR波后ST段抬高,T波正立)作者分析二组急性心肌梗塞病人,一组217人心电图上无M复合波(非M组),另一组58人有M复合波(M组)。对49例(M组37例,非M组12例)每4小时作心电图一次
ECG changes in acute myocardial infarction with or without prognostic significance, the current different views. The authors point out in this article that the appearance of an electrocardiogram sign-M complex is often accompanied by a variety of complications and is an indication of poor prognosis. The so-called M complex is a single-phase waveform qRST wave. (Abstract Note: refers to ST-segment elevation after qR wave, T wave is erected) Analysis of the two groups of patients with acute myocardial infarction, a group of 217 patients without M complex electrocardiogram (non-M group), another group of 58 people have M complex wave (M group). 49 cases (M group 37 cases, non-M group 12 cases) every 4 hours for ECG
