【摘要】 近年来，饮酒变得越来越普遍。然而，酒精对身体的作用仍然在研究中。许多研究表明，酒精能够影响自主神经的活动，饮酒后，心电图显示心率变异会发生变化。研究酒精对自主神经及心率变异的影响，为酒精性疾病的诊断及其治疗效果的判断提供了一条新的途径。在这篇文章中，我们将阐述酒精对自主神经的作用机制及对心率变异的影响的研究进展，还会提到在停止饮酒后，心率变异会有哪些变化。

    【Abstract】 In recent years, more and more people use alcohol, but the effect of alcohol on the body is still in study. A lot of studies shows that alcohol can affect the activity of the autonomic nerve. Heart rate variability(HRV) changes in the electrocardiogram after dringking. The significance of studying the effect of alcohol on the autonomic nerve and heart rate variability is to provide a new method for the diagnosis of alcohol relating diseases and evaluation of the therapeutic effect. In this article,we will state the mechanism of alcohol acting on the autonomic nerve and the effect of alcohol on heart rate variability. We will also elicit how the HRV changes during alcohol abstinence.

    心率变异性(heart rate variability,HRV)是指逐次心动周期之间的微小变化，即窦性心律不齐的程度。众所周知正常人的心率并不是绝对规则的，它受许多因素如运动、呼吸、血压、体温及精神紧张的影响而变化 ......
