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、QTcd对患者近期严重室性心律失常的发生有预测意义
Objective: To investigate the relationship between QT interval dispersion, JT interval dispersion and severe arrhythmia in early AMI. Methods: The QTd and JTd of QTd and JT were measured at the 3rd day after myocardial infarction in 46 AMI patients. And compared with 30 normal controls. Results: The QTd, JTd and QTcd in AMI group were significantly higher than those in control group (P <0.01). QTd, JTd and QTcd in the group of severe ventricular arrhythmia (18 cases) during hospitalization were significantly higher than those in the group without severe ventricular arrhythmia (28 cases) (P <0.01), and the incidence of ventricular fibrillation was 9 Patients with QTd, JTd, QTcd significantly increased compared with no ventricular fibrillation (P <0.01). Conclusions: QTd, JTd and QTcd in early AMI patients have predictive value for the occurrence of severe ventricular arrhythmia in recent years
