目的观察前庭刺激状态下胃电图的变化特征。方法记录了２５名转椅Ｃｏｒｉｏｌｉｓ刺激、２８名冷热刺激下飞行员的胃电图。结果５３名被试者在刺激过程中胃电发生了明显的节律紊乱，表现为胃动过速百分率增高（Ｐ＜０．０５）；在Ｃｏｒｉｏｌｉｓ刺激中，重度症状组的主频由正常的２．４０～３．７０周／ｍｉｎ（ｃｐｍ）上升到３．７０～１０．００ｃｐｍ的范围内，且随着症状加重而上升明显、持续时间愈长的趋势。结论主频可成为评价运动病严重程度的一项重要参数指标。
Objective To observe the changes of gastric electrogastrogram under vestibular stimulation. Methods Twenty-five Coriolis swings and 28 electrocardiographs of pilots were recorded. Results Fifty-five subjects had significant rhythm disturbance of gastric electrical activity during stimulation, which showed an increase in the percentage of gastric motility (P <0.05). In Coriolis stimulation, the frequency of severe symptoms was increased from normal 2 .40 ~ 3.70 weeks / min (cpm) increased to 3.70 ~ 10.00cpm within the range, and with the symptoms increased significantly increased, the longer the trend. Conclusion Frequency can be an important parameter to evaluate the severity of motion sickness.
