前庭刺激症状与胃电图相关分析

EGG and Nausea Under Vestibular Stimulus.

对８１名男性歼、强击机飞行员前庭器官施加科里奥利加速度刺激，按其有无恶心（含呕吐）症状分为甲、乙两组。甲组４３人，为无恶心症状组。乙组３８人，为有恶心症状组。通过对这两组胃电图节律的胃动过缓、正常节律、胃动过速以及主频、主幅和主幅不稳定率等六项参数的对比分析，结果发现胃动过缓和正常节律所占百分率的大小同恶心症状出现有关。

pilots were exposed to vestibular stimulus with Coriolis acceleration.They were divided into two groups,the first group consisted of 38 pilots with nausea symptoms,the second group 43 pilots without nausea symptom.Dominant frequency instability coefficient (DFIC),dominant power instability coefficient(DPIC), Tachygastria, Bradygastria and normal slow wave components(NSW) of the electrogastrogram(EGG) were analyzed.The results showed that Bradygastria and NSW of EGG were related to nausea symptom of pilots under Cariolis stimulation.
