摘要
目的探讨陈旧性心肌梗死发病后对心率变异(HRV)的影响。方法 86例陈旧性心肌梗死患者为陈旧性心梗组,选择78例年龄及性别与陈旧性心肌梗死组相匹配的健康志愿者为对照组。入选的患者及健康志愿者进行24h动态心电图监测,采用计算机分析系统对HRV时域指标(NN、SDNN、SDANN、RMSSD、PNN50)及频域指标(VLF、LF、HF、LF/HF)进行分析。结果与对照组比较,陈旧性心肌梗死组患者HRV的各项指标均较对照组显著降低(P<0.05)。结论陈旧性心肌梗死患者存在心血管自主神经系统功能紊乱现象。
Objective To investigate the effect of old myocardial infarction on the heart rate variability.Methods Totally 86 patients with old myocardial infarction and 78 healthy people were enrolled in the study.Twenty-four-hour heart rate variability in the time domains including NN,SDNN,SDANN,RMSSD,and PNN50 and the frequency domains including VLF,LF,HF,and LF/HF were analyzed.Results Both the time domain and frequency domain indexes of the heart rate variability in patients with old myocardial infarction significantly decreased than those in the healthy peolple（P 0.05）.Conclusion There might be autonomic nervous system dysfunction in the patients with old myocardial infarction.
