【摘要】：目的分析心率变异性(heart rate variability,HRV)与晕船病的关系,探索预测晕船病易感性的生理指标。方法采集58名健康受试者陆上安静状态下和海上航行中的的短程心率变异指标,根据航海中是否出现晕船反应分为晕船病组26人和不晕船对照组32人。应用心率变异性时域、频域分析方法,分别评价其自主神经功能状态。结果海上航行中,晕船病组心率变异性时域指标明显高于对照组:RR间期平均值(MRR)增高21.26%,RR间期平均值的标准差(SDNN)增高27.75%,相邻RR间期差值的标准差(rMSSD)增高18.42%,相邻RR间期相差大于50ms占总心动周期的百分比(PNN50)增高32.14%,心率变异性指数(HRVI)增加24.05%。心率变异频域指标中,晕船病组与对照组比较,低频带(LF)增高81.98%,高频带(HF)增高13.59%,总功率谱密度(TP)增加32.43%,LF与HF比值(LF/HF)降低31.82%。在陆地上安静状态下,晕船病组心率变异性指标与对照组比较:SDNN、PNN50、HRVI分别增加26.68%、30.32%、30.48%,VLF、LF、HF、TP分别增加31.82%、45.05%、41.98%、37.62%;LF/HF降低32.43%。结论自主神经功能在运动病的发生中起着重要作用。晕船病者固有的自主神经张力较高,而且在发生晕船病时自主神经张力明显增高,特别是以迷走神经张力为主。心率变异性检测可以作为预测晕船病易感性的一个重要指标。
[Abstract]:Objective to analyze the relationship between heart rate variability (HRV) and seasickness, and to explore the physiological indexes to predict the susceptibility of seasickness. Methods Short-range heart rate variability (HRV) indexes of 58 healthy subjects were collected. According to whether there was seasickness in navigation or not, they were divided into seasickness group (n = 26) and non-seasick control group (n = 32). Time domain and frequency domain analysis of heart rate variability (HRV) were used to evaluate the autonomic nervous function. As a result, The time domain indexes of heart rate variability in seasickness group were significantly higher than those in control group. The mean value of RR interval was increased by 21.26%. The standard deviation of RR interval was increased by 27.75%, and the standard deviation of adjacent RR interval was increased by 18.42%. The difference of adjacent RR interval was greater than that of 50ms. The percentage of cardiac cycle (PNN50) increased 32.14 and HRVI increased 24.05. Compared with the control group, the frequency domain index of heart rate variability (HRV) in seasickness group was 81.98% higher than that in control group, HFR in high frequency band was increased 13.59%, total power spectral density (TPTP) was increased 32.43% and LF / HF ratio was increased 32.43% (LF- / HFR) decreased 31.82%. In the quiet condition on land, the HRVI of the seasickness group was increased by 26.68 and 30.32, respectively, compared with that of the control group. Compared with the control group, the HRVI of the seasickness group was increased by 31.82N / 45.05 / 41.98 / 37.62LF/ HF, respectively, and 32.43% lower than that of the control group. Conclusion autonomic nervous function plays an important role in the development of motor disease. The autonomic nervous tension of seasickness patients was higher than that of seasickness patients, especially vagus nerve tension. Heart rate variability can be used as an important index to predict the susceptibility to seasickness.
