Premenstrual syndrome (PMS) is a group of psycho behavioural symptoms experienced by many susceptible young women prior to menstruation. It is suggested that there is altered autonomic activity in the late leuteal phase of their endometrial cycle. The present study is aimed to see the autonomic reactivity in women suffering from PMS and to compare it with control ones. The results revealed that the autonomic activity-sympathetic as well as parasympathetic, is insignificantly higher in PMS group during follicular phase. During leuteal phase, the parasympathetic activity is significantly lowered but the sympathetic activity is significantly increased. A positive correlation was also seen between both limbs of autonomic system with number of symptoms. It appears that increased sympathetic activity coupled with decreased parasympathetic activity during the leuteal phase might be responsible for psycho- physiological changes in these women. However, the exact mechanism is still unknown.
经前综合征（PMS）是许多易患此病的年轻女性在月经前经历的一组心理行为症状。有人认为，在她们子宫内膜周期的黄体晚期，自主神经活动会发生改变。本研究旨在观察经前综合征女性的自主神经反应性，并将其与对照组进行比较。结果显示，在卵泡期，经前综合征组的自主神经活动——交感神经和副交感神经活动均略高于对照组。在黄体期，副交感神经活动显著降低，但交感神经活动显著增加。自主神经系统的两个分支与症状数量之间也存在正相关。看来，黄体期交感神经活动增加以及副交感神经活动减少可能是这些女性心理生理变化的原因。然而，确切机制仍不清楚。
