| 摘 要： | 132例急性心肌梗塞患者入院及出院时体表心电图Q-Tc间期的变化,与冠心病组、心律失常组及正常对照组比较,结果发现急性心肌梗塞患者入院时Q-Tc间期较出院时明显延长(P<0.01);较冠心病组、心律失常组及正常对照组亦显著延长(P<0.01)。Q-Tc间期≥440ms的急性心肌梗塞患者病死率为20.41%,较Q-Tc间期<440ms的急性心肌梗塞患者病死率(8.23%)明显增高(P<0.05)。提示Q-Tc间期可做为观察急性心肌梗塞患者病情及其恢复情况的参考指标,对评价急性心肌梗塞患者的预后。

| Abstract: | The changes of Q-Tc interval in 132 cases of acute myocardal infarc-
tion (AMI) on admission and discharged were analysed, and were comp-
ared with coronary heart disease group, arrhythmia group and normal
contral group. The results showed that on admission Q-Tc interval of
AMI was obviously longer than that of AMI on discharged (P<0.01),
and also longer than that of coronary heart disease group, arrhythmia
group and normal contral group (P<0.01). Mortality of patients with
AMI whose Q-Tc interval equal or longer than 440ms was 20.41%, which
increased significantly than that of patients with AMI whose Q-Tc
interval was shorter than 440ms, which was 8.23%. The findings suggest
that Q-Tc interval may be a parameter for observing clinical status of
patients with AMI and their recovery and it also was of great value in
evaluating the prognosis of AMI. |
