心肌梗塞是冠心病最严重的一种病理类型,也是冠心病致死的主要原因。除由于心电不稳造成猝死外,主要是左心室泵衰竭(急性左心衰竭及心源性休克)。经临床及动物试验证实,与梗塞范围(IS)有关,IS越大,预后越差,因此,对I S大小的判断及余留心肌功能的估计,就显得十分重要和迫切,用常规心电图方法只能确定有否梗塞存在及明确梗塞的部位,不能作定量分析。Marok首先用心前区多导联心电图标测法,观察犬冠状动脉结扎后体表心电图ST段上升总和(∑ST)与IS的关系。其后,Awan等用同样方法标测前壁
Myocardial infarction is the most serious type of coronary heart disease, but also the main cause of death from coronary heart disease. In addition to sudden death due to unstable ECG, the main failure of left ventricular pump (acute left heart failure and cardiogenic shock). Clinical and animal experiments confirmed that, with the infarct size (IS), IS, the greater the worse the prognosis, therefore, to judge the size of the IS and the remaining myocardial function estimates, it is very important and urgent, with conventional ECG method only Can determine whether the presence of infarction and infarction sites, can not be used for quantitative analysis. Marok first multinuclear electrocardiogram (ECG) in precordial area was used to observe the relationship between the sum of ST ST elevation (Σ ST) and IS in the canine coronary artery ligation. Later, Awan et al used the same method to label the anterior wall
