心电图检查是协助诊断冠心病的重要方法,特别是对急性心肌梗塞的确诊有其独特的价值。现仅从心电图角度如何使各种类型的冠心病患者得到早期诊断问题,分别就心绞痛、心电图运动试验、不典型心肌梗塞以及陈旧性心肌梗塞的诊断,谈谈一些看法。心绞痛冠心病患者出现像教科书所描述那样的典型心绞痛症状的并不多。而约有一半患者,平静检查的心电图是正常的,为了更早期地发现这些病人,常须进行心电图负荷试验(见后)。在一些平静心电图能出现的改变中比较多见的是一些带有特征性的ST-T改变,这是广大医务工作者所熟知的,现提 ECG is an important method to help diagnose coronary heart disease, especially for the diagnosis of acute myocardial infarction has its unique value. Now only from the ECG point of view how to make all types of patients with coronary heart disease early diagnosis, respectively, angina, electrocardiogram exercise test, atypical myocardial infarction and the diagnosis of old myocardial infarction, to talk about some views. Angina patients with coronary heart disease appear as typical textbooks described typical angina symptoms are not many. In about half of patients, electrocardiographic examination of the sedation is normal, and an ECG load test (see below) is often required in order to detect these patients earlier. In some changes can be more peaceful electrocardiogram changes are some of the characteristics of ST-T changes, which is well known to the majority of medical workers, is to mention
