多年来,临床上一直把心肌梗塞分为透壁性和非透壁性(或内膜下)心肌梗塞两大类,其区别是心电图(BCG)是否出现病理性Q波。但许多学者通过大量动物试验和病理解剖研究发现:有明确Q波的前壁和下壁AMI其梗塞深度可只局限于心内膜下。Coor等通过实验也证实梗塞仅累及左室厚度的1/2便可引起Q波。Durrer等在狗的心外膜进行测定发现;即使梗塞直径<1cm,深度仅达室壁厚度的1/4,也可在EOG上记录到Q波。ECG上出现病理
For many years, myocardial infarction has been divided into two categories: transmural and non-transmural (or submerged) myocardial infarction. The difference is whether pathological Q wave appears in ECG. However, many scholars through a large number of animal experiments and pathological anatomy found that: a clear Q waves of the anterior and inferior AMI infarction depth can be confined to the subendocardial. Coor and other experiments also confirmed that infarction involving only 1/2 of the left ventricular thickness can cause Q wave. Durrer et al. Found in the dog’s epicardium that a Q wave was recorded on the EOG even with an infarct diameter of <1 cm and a depth of only 1/4 of the wall thickness. Pathology on ECG
