摘　　要：目的 :观察QT间期离散度 (QTd)及JT间期离散度 (JTd)在急性心肌梗塞溶栓治疗前后的变化。方法 :我们将64例施溶栓治疗的急性心肌梗塞 (AMI)病人分为2组 :再通组42例 ,未通组22例。测定和计算溶栓前及溶栓后2、8、24、48小时和1周的同步12导联心电图QTd及JTd并比较它们的变化。结果 :溶栓前再通组与未通组QTd、JTd相比无显著差异 (P>0 05)。溶栓后 ,再通组与未通组各对应时间相比 ,有显著差异 (P<0 01)。结论 :成功的溶栓治疗可使QTd、JTd明显缩短 ,QTd。Objective:To observe the variations of QTd and JTd before and after early intravenous thrombolytic therapy in patients with acute myocardial infarction.Metheds:64 cases of acute myocardial infarction treated with intravenous thrombolytic therapy were divided into two groups,namely unobstructed group was 42 cases.obstructed group was 22 cases.The QTd and JTd were detected and calculated before and after early thrombolytic therapy with synchronous 12 lead electrocardiography,their variations were compared at the same time.the QTd and JTd were specially observed on 2?8?24?48h and 1 week after thrombolytic therapy.Results:There was no significant difference between them before thrombolytic therapy(P>0 05),but it showed statistical difference after thrombolytic therapy.Conclusion:The QTd and JTd can be obviosly shortened if the thrombolytic therapy is successful.The variation of QTd and JTd can be a index of non-trauma to judge the success of thrombolysis [
