传统看法,认为只有透壁性心肌梗塞才能出现异常 Q 波。且一旦形成,常持续存在。但近年来研究表明病理性 Q 波,仅表示局部心肌电激动的丧失。于心肌细胞坏死时,可呈永久性 Q 波;倘若心肌缺血损害是可逆的,当其血重新获得血流灌注时,则病 The traditional view, that only transmural myocardial infarction in order to appear abnormal Q waves. And once formed, often persists. But in recent years, studies have shown that pathological Q wave, said only the loss of local myocardial electrical stimulation. In cardiomyocytes necrosis, can be a permanent Q wave; if the myocardial ischemia damage is reversible, when the blood regained blood flow, then the disease
