传统观点认为体表心电图上的病理性Q波是透壁心肌梗死和瘢痕组织形成的标志,而且与预后密切相关。和非Q波心肌梗死相比,Q波心肌梗死可以显著增加患者的近期和远期死亡率。但近年来随着溶栓剂、PCI术、冠状动脉旁路移植术的广泛应用,部分透壁心肌梗死的患者并不出现病理性Q波。Q波心肌梗死比例已由原来的66.6%降至现在的37.5%[1],而非Q波心肌梗死的比例相应增 The traditional view that pathological Q wave on the body surface electrocardiogram is a sign of transmural myocardial infarction and scar tissue formation, but also with the prognosis are closely related. Compared with non-Q wave myocardial infarction, Q wave myocardial infarction can significantly increase the short-term and long-term mortality in patients. But in recent years, with thrombolytic agents, PCI, coronary artery bypass grafting widely used, partial transmyocardial infarction patients do not appear pathological Q wave. Q-wave myocardial infarction ratio has dropped from the original 66.6% to 37.5% [1], while the proportion of non-Q-wave myocardial infarction increased accordingly
