摘要
目的 :比较AMI溶栓治疗前后QT离散度的变化 ,评价溶栓治疗对AMIQTd的影响。方法 :测定急性心肌梗死病人溶栓前后心电图的QTd和QTcd。结果 :急性心肌梗死溶栓前QTd为 5 8 43± 8 84ms ,溶栓后为 3 4 3 5±10 .62ms(P <0 .0 1) ;溶栓前QTcd为 61 49± 12 .0 3ms ,溶栓前为 3 8 72± 10 .3 1ms(P <0 .0 1)。结论 :溶栓治疗能够明显缩短QTd和QTcd ,可能与梗死血管再通 。
Objective: To compare the changes of QT dispersions(QTd) before and after acute myocardial infarction (AMI) in order to assess the effect of thrombolysis on QTd of patients with AMI.Methods: To measure QTd and QTcd of electrocardiogram in patients with acute myocardial infarctin before and after thrombolysis.Results: Before the thrombolytic therapy,the QTd of patients with AMI was 58.43±8.84 ms,while after thrombolytic therapy,it was 34.35±10.62 ms ( P<0.01) .Before the thrombolytic therapy,the QTcd of patients with AMI was 61.49±12.03 ms,while after thrombolytic therapy,that was 38.72±10.31 ms ( P<0.01). Conclusion: Thrombolysis therapy could obviously shorten the duration of QTd and QTcd,which may be associated with patency of infarct related artery and reperfusion of myocardial cells.
