摘　　要：目的探讨植物神经功能与急性心肌梗塞（ＡＭＩ）的关系。方法用５ｍｉｎ节段采样分析的心率功率谱检查方法测定了４０例ＡＭＩ患者（ＡＭＩ组）和４１例正常对照者（对照组）的植物神经功能。结果ＡＭＩ组较对照组高频峰（ＨＦＰ）降低（Ｐ＜０．０１），低频峰（ＬＦＰ）／ＨＦＰ增高（Ｐ＜０．０１）；且于ＡＭＩ后３月时ＨＦＰ仍不能恢复正常；前壁ＡＭＩ患者ＨＦＰ降低明显（Ｐ＜０．０１），ＬＨＰ／ＨＦＰ高于非前壁梗塞者（Ｐ＜０．０１）。结论ＡＭＩ患者迷走神经功能受损，植物神经功能失调，并且前壁ＡＭＩ迷走神经活性低于下、后壁ＡＭＩ患者，ＡＭＩ后迷走神经功能短时间内不能恢复正常，很可能是永久性损害。Objective To study the relation of the autonomic nervous activity and acute myocardial infarction.Method The autonomic nervous activity in patients with actue myocardial infarction(AMI) and normal subjects were studied with heart power spectral analysis.Result [WT5BZ〗The patients with AMI had much lower high frequency power (HFP),higher the ratio of low frequency power to high frequency power (LFP/HFP) compared to normal subjects (both P<001).HFP cannot recover completely in two weeks and 2～3 months after AMI.HFP is lower and LFP/HFP higher in patients with anterior AMI than non-anterior AMI (both P<001).Conclusion Vagal activity is decreased and cardiac autonomic nervous system is disorder in patients with AMI.Decreased vagal activity is associated with infarct site.Vagal activity may be damaged forever.
