对急性心肌梗塞(AMI)的诊断,ECG具有任何现代先进诊断技术所不能取代的作用。但在梗塞面积的估计,梗塞后心室功能的测定以及闭塞冠脉的识别方面 ECG 作用如何呢?本文就这些问题作一综述介绍。一、对梗塞面积的估计普遍认为 AMI后症状严重性及其预后,很大程度上取决于梗塞面积,因此如何及时准确地对梗塞面积作出估计,临床上具有非常重要的意义。目前国外有许多估计 MI 面积的方法,如 CK- The diagnosis of acute myocardial infarction (AMI), ECG has no modern advanced diagnostic technology can not replace the role. But what about the ECG effect in the estimation of infarct size, the determination of post-infarction ventricular function and the identification of occluded coronary arteries? This article reviews these questions. First, the estimation of infarct size It is generally agreed that the severity of symptoms and their prognosis after AMI depend largely on infarct size. Therefore, it is clinically important to estimate the infarct size timely and accurately. At present there are many foreign methods to estimate MI area, such as CK-
