前庭刺激对飞行人员心率变异的影响

为探讨前庭刺激对飞行人员的心率变异性（ＨＲＶ）及植物神经功能的影响，对两组飞行员在不同强度的科里奥利加速度刺激时，用时域分析和频域分析法对实验前和实验中的ＨＲＶ进行了检测和分析。结果表明；原始均值，标准差，最小值，最大值，极差，相关均值，Ｒ－Ｒ间期差值的均方根（ＲＭＳＳＤ），谱总功率（ＴＰ），低频（ＬＦ），高频（ＨＦ），ＬＦ／ＴＰ，ＨＦ／ＴＰ，ＬＦ／ＨＦ均有不同程度的增加（Ｐ〈０．０５～０．０１）

Effects of Vestibular Stimulus on Heart Rate Variability.

Possible effects of vestibular stimulation autonomic nerve function in pilots were studied by observing changes of Heart Rate Variability (HRV). Time domain and frequency domain analyses demonstrated that the primarily averages, standard deviation of the HRV averages(SD), least or greatest value, deviation of greatest minus least value, interrelated averages, square root of the mean of the sum of squares of differences between adjacent R-R intervals (RMSSD), total power(TP), low frequency(LF), high frequency(HF), LF/TP, HF/TP, and LF/HF all had significant increase or decrease (P <0.05 - <0.01) and the degrees of changes were related to the intensity of the stimulations.
