摘　　要：目的 :探讨AMI早期QT间期离散度、JT间期离散度与严重心律失常的关系。方法 :测定 46例AMI患者心梗发生后第 3d的QT间期离散度 (QTd)和JT间期离度 (JTd)。并与30例正常人的对照组比较。结果 :AMI组QTd、JTd、QTcd较对照组显著增大 (P <0 0 1 )。住院期间严重室性心律失常发生组 (1 8例 )的QTd、JTd、QTcd较无严重室性心律失常组 (2 8例 )明显增大 (P <0 0 1 ) ,且发生室颤的 9例患者QTd、JTd、QTcd比无室颤的明显增大 (P <0 0 1 )。结论 :早期测定AMI患者QTd、JTd。Objective:To discuss the relation between the dispersion degree of QT interval (QTd) and JT interval (JTd) of early AMI and severs arrhythmia.Methods:The QTd and JTd of early AMI at third day were detected and compared with the value of 30 normal persons.Results:The QTd,JTd and JTcd in AMI group were obviously increased than control group (P<0 01).The QTd,JTd and JTcd in severe arrhythmia group were higher than the group without arrhythmia (p<0 01).The TDd,JTd and JTcd with ventricular fibrillation were more increased than that without fibrillation (p<0 01).Conclusion:The detection of QTd,JTd and JTcd for early AMI patient might predict the happening of severe ventricular arrhythmia.
