摘要
目的 测量急性首次Q波心梗病人的QT离散度的变化并分析美托洛尔对此类病人QTd的影响。方法 对 6 8例急性首次Q波心梗病人做体表 12导联同步心电图 ,测量QTd ,并与 30例健康成人对照 ;再将 6 8例急性首次Q波心梗病人应用美托洛尔治疗前及治疗后 4周的QTd加以对比。结果 急性首次Q波心梗组与健康成人组QTd差异有显著意义 (P <0 0 1) ,心梗组用美托洛尔治疗前后QTd差异有显著意义(P <0 0 1)。结论 急性首次Q波心梗病人QTd显著增加 ,美托洛尔可降低此类病人QTd。
Objective To analyse the changes of QTd of cardiogram in patients with first Q-wave acute myocardial infarct(AMI) and the effect of metoprolol treatment on QTd.Methods QTd in 68 patients with first Q-wave AMI was measured by using body surface synchronical 12 leads cardiogram and compared the results with that of 30 healthy adults.QTd in 68 patients with first Q-wave AMI before motoprolol treatment was compared with that after metoprolol treatment for 4 weeks.Results The QTd difference between the group of patients with first Q-wave AMI and the group of healthy adults was remarkble(P<0.01).Conclusion QTd in patients with first Q-wave AMI increases obviously which may be decreased due to metoprolol treatment.
