大规模多中心研究表明［１］，急性心肌梗死（ＡＭＩ）的早期再灌注可以缩小梗死面积，改善ＡＭＩ的预后。Ｑ－Ｔ离散度是指心电图各导联Ｑ－Ｔ时限变异的程度，是反映心室肌应激性恢复的重要指标，对预测ＡＭＩ后心室颤动的发生有重要的价值［２］。我们通过分析静脉溶栓治疗?
Large-scale multicenter studies have shown that [1] early reperfusion of acute myocardial infarction (AMI) can reduce the infarct size and improve the prognosis of AMI. Q-T dispersion refers to the degree of Q-T variation of each lead of electrocardiogram and is an important index reflecting the recovery of ventricular muscle stress. It is of great value in predicting ventricular fibrillation after AMI [2]. We pass the analysis of intravenous thrombolytic therapy?
