应用心电图记分法评价心肌梗死T波早期倒置的意义

Use of QRS scoring system for estimating early T wave inversion in patients with mycocardial infarct

对接受静脉溶栓治疗、临床评价再通的56例急性心肌梗死（MI）患者应用心电图记分法估计溶栓治疗前后MI的面积，并计算MI面积挽救程度；按有无T波早期倒置分为两组，进行统计学分析，发现有显著差异（P＜0．05）。提示存在T波早期倒置现象的患者，冠状动脉开通更充分、心肌能获得更充分再灌注，可作为估计预后及是否进一步干预治疗的证据。

A QRS scoring system was used to estimate myocardial infarct size of 56 AMI patients,before and after thrombolytic therapy as well as the amount of rescued jeopardized myocardium assessed. They were divided into two groups due to with or without early T wave inversion.The group with early T wave inversion was superior to the group without early T wave inversion in the amount of rescued jeopardized myocardium (P <0. 05). The results suggest that early T wave inversion after thromblytic therapy predicts better coronary perfusion. It may be useful in estimating prognosis and determining whether or not the use of further therapeutics.
