摘　　要：目的探讨急性心肌梗死(AMI)患者Q-T间期离散度(Q-Td)和J-T间期离散度(J-Td)的变化及对AMI预后的影响。方法选择近年住院资料完整的AMI患者163例,分为存活组和死亡组,分别进行Q-Td及J-Td对比测量,并与正常对照组进行比较。结果AMI组Q-Td、J-Td均较正常对照组显著增加,住院期间死亡组Q-Td、J-Td较存活组有显著增加。结论AMI时Q-Td、J-Td显著增加,死亡者较存活者增加更为显著,此可作为识别AMI后高危人群的一个有价值的指标。Objective To discuss the changes of Q-T diffusion（Q-Td）and J-T diffusion （J-Td） in patients with acute myocardial infarction （AMI）and the effects. Methods One hundred sixty-three AMI patients who had been in hospital in recent years and all complete records, were divided into the dead group and the survival group. Q-Td and J-Td contrastive measurement was made on them, and then comparison was made with the control group, Results Q-Td and J-Td increase more remarkably in the AMI group than in the control group. Q-Td and J-Td increase more remarkably in the dead group than in the survival group. Conclusion Q-Td and J-Td increase remarkably in AMI group, and increase more remarkably in the dead group than in the survival group. The finding of this study could be a valuable guideline for distinguishing from patients with AMI on the edge of danger.
