摘　　要：目的　探讨心率变异性与运动病的关系。方法　根据出海实习学员运动病的发生情况 ,将学员分为运动病组和对照组各 2 0人 ,采集安静状态下的 5 2 0次窦性心搏 ,应用心率变异时域、频域分析方法评价自主神经功能状态。结果　运动病组时域指标 RR间期平均值的标准差 (SDNN)、相邻 RR间期差值的均方根 (r MSSD)、相邻 RR间期相差大于 5 0 m s占总心动周期数的百分比 (PNN50 )、HRV指数(HRVI)和频域指标低频 (L F)、高频 (HF)、总功率谱密度 (TP)均显著高于对照组 (P<0 .0 5 )。 RR间期平均值 (MRR)、极低频 (VL F)、低频与高频的比值 (L F/ HF)在两组间差异无显著性 (P>0 .0 5 )。结论　自主神经功能状态对运动病的发生存在明显的影响 ,迷走神经张力过高与运动病的发生有密切关系。心率变异性检测可以作为运动病易感性重要的预测指标。Objective To investigate the correlation between heart rate variability and motion sickness. Methods 520 RR intervals were collected from 20 subjects with motion sickness and 20 normal volunteers. Short time heart rate variability includes time domain, frequency domain analysis methods. Results In subjects with motion sickness, the indices of time domain of SDNN, rMSSD, PNN 50 , HRVI and the subscripts of frequency domain of LF, HF, TP were significantly higher than those of the control ( P <0 05). With regard to MRR, VLF and the ratio of LF/HF, there were no remarkable differences between the subjects and the control ( P >0 05). Conclusions The state of the autonomic nerve system has no significant effect on the occurrence of motion sickness. High tension in the vagus nerves is closely correlated with motion sickness. Measurement of heart rate variability might be an important indicator for the prediction of susceptibility of motion sickness.
