The characteristics of 93 patients in whom electrocardiographic recordings were obtained within 12 hours of the onset of non-Q-wave myocardial infarction were studied. Patients were divided into the three groups according to what electrocardiographic changes were seen. Forty nine patients had ST segment depression, 35 had ST segment elevation, and nine had T wave changes. Patients with ST segment depression had a higher rate of pump failure and multivessel disease than the other two groups. There were no significant differences in peak serum creatine kinase activity among the three groups. Twelve of 13 patients who died of non-Q-wave myocardial infarction in hospital had ST segment depression. Furthermore nine of them had attacks of non-Q-wave myocardial infarction with severe ST segment depression in many leads. At necropsy five of six patients who had shown severe ST segment depressions in many leads at the onset of non-Q-wave myocardial infarction were found to have circumferential subendocardial lesions with triple vessel disease. This study suggests there are electrocardiographic subtypes of non-Q-wave myocardial infarction that are associated with specific patient characteristics.
对93例在非Q波型心肌梗死发作12小时内进行心电图记录的患者的特征进行了研究。根据观察到的心电图变化将患者分为三组。49例患者出现ST段压低，35例出现ST段抬高，9例出现T波改变。ST段压低的患者比其他两组有更高的泵衰竭发生率和多支血管病变发生率。三组之间血清肌酸激酶峰值活性无显著差异。13例在医院死于非Q波型心肌梗死的患者中有12例出现ST段压低。此外，其中9例有非Q波型心肌梗死发作，多个导联出现严重ST段压低。尸检发现，6例在非Q波型心肌梗死发作时多个导联出现严重ST段压低的患者中有5例有环形心内膜下病变和三支血管病变。这项研究表明，非Q波型心肌梗死存在与特定患者特征相关的心电图亚型。
