【摘要】：目的应用心率变异性(HRV)探讨自主神经功能与急性高原反应(AMS)症状学评分的相关性。方法86例健康汉族男性新兵在平原560m和空运至海拔3675m西藏高原2～4d内,分别接受了短程HRV检测,进藏后当日接受了AMS症状学评分调查。根据该评分将受试者分为基本无AMS组(49例)和AMS组(37例)。结果AMS组平原HRV中平均正常RR间期的标准差(SDNN)、相邻RR间期差的均方根(rMSSD)、低频(LF)以及急进高原rMSSD、SDNN、LF、总功率(TP)、相邻RR间期相差50ms百分数(PNN50)的下降幅度均显著高于基本无AMS组(P0.05,P0.01),但其平原标准化高频(HFnu)则显著低于后者(P0.05)。AMS症状学评分与平原rMSSD、SDNN、LF/HF以及急进高原rMSSD、SDNN变化幅度均呈正相关(P0.05),但与平原HFnu呈负相关(P0.01)。结论自主神经功能与AMS相关,平原自主神经活性较高、交感神经占优势且对应激反应过强者AMS症状较重,检测心率变异性可在一定程度上预测AMS。
[Abstract]:Objective to investigate the correlation between autonomic nervous function and (AMS) symptom score of acute high altitude reaction by heart rate variability (HRV). Methods 86 healthy male recruits of Han nationality were tested for short range HRV within 2 days from 560m plain and 3675m altitude to Tibet plateau. The AMS symptom score was investigated on the same day after entering Tibet. According to the score, the subjects were divided into two groups: the basic no AMS group (49 cases) and the AMS group (37 cases). Results the standard deviation of mean normal RR interval in plain HRV of AMS group was the root mean square (rMSSD), low frequency (LF) of (SDNN), adjacent RR interval difference and the rMSSD,SDNN,LF, total power (TP), of rapid entry plateau. The decrease of 50ms percentage (PNN50) of the adjacent RR interval was significantly higher than that of the non-AMS group (P0.05, P0.01), but the plain standardized high frequency (HFnu) was significantly lower than the latter (P0.05). AMS symptom score and plain rMSSD,SDNN,). The changes of LF/HF and rMSSD,SDNN were positively correlated (P0.05), but negatively correlated with plain HFnu (P0.01). Conclusion the autonomic nerve function is related to AMS, and the autonomic nerve activity is higher in plain, and the sympathetic nerve is dominant and the symptoms of AMS are more serious than those with strong stress response. Heart rate variability can be used to predict AMS. to some extent.
