心绞痛与心肌梗死患者的心率变异性分析

The comparison of heart rate variability in patients with angina and myocardial infarction

目的 :探讨心绞痛及心肌梗死 (MI)患者的自主神经活动特点。方法 :对 30例健康者 ,2 5例心绞痛 ,2 0例陈旧性心肌梗死 (OMI) ,30例急性心肌梗死 (AMI)患者的心率变异性进行了对比研究。结果 :心绞痛以及 MI患者的心率变异性明显低于正常人 ,AMI者低于心绞痛以及 OMI患者。结论 :冠心病患者的自主神经活动受损 ,AMI患者更加明显 ,其迷走神经张力降低 ,而交感神经紧张性相对增强 ,发生恶性室性心律失常的危险性增加。

To study the autonomic nerve system character in different kinds of CHD patients.Method:Compared the heart rate variability (HRV) of 25 angina pectoris,20 OMI,30 AMI patients and 30 normal controls.Result:The HRV of CHD patients was lower than that of the normal controls,and the AMI patient were the lowest.Conclusion:The autonomic never system function of CHD patients is damaged,and the AMI patients is the most,and the probability of vertricular arrhythmic events is higher.
