心肌梗塞患者的预后与心肌梗塞范围大小关系密切,动态了解梗塞范围的变化对于指导治疗及判断预后都有重要意义。常规心电图应用于心肌梗塞的定性及定位诊断,已近半个世纪。1972年,Selvester 等经大量动物试验后成功地用计算机模拟人体心电活动,用减去某一模拟电偶的方法,再现了不同部位梗塞时的心电学改变,描出类似于心肌梗塞的心电图及心电向量图图形。并提出一种根据常规心电图 QRS 波的定量分析可
The prognosis of patients with myocardial infarction and myocardial infarction size is closely related to the dynamic understanding of the changes in infarct size for guiding the treatment and prognosis are of great significance. Conventional ECG used in the qualitative and localization of myocardial infarction diagnosis, nearly half a century. In 1972, Selvester and other experiments after a large number of animals successfully using the human body to simulate the activity of the human body, with a subtraction of a simulated galvanic couple method to reproduce the ECG changes in different parts of infarction, depicting myocardial infarction-like ECG and ECG vector illustration graphics. And proposed a quantitative analysis based on QRS wave of conventional electrocardiogram
