【摘要】：目的探讨自主神经系统(ANS)功能在急性高原反应(AMS)发病中的意义。方法43名健康青年男性在完成进舱前的5min短程心率变异性(HRV)、冷加压试验(CPT)及血浆去甲肾上腺素(NA)浓度检测后,进入低压氧舱模拟急进海拔4500m1天。所有受试者在模拟高原第2、10、20h接受HRV动态检测,并再次接受CPT及NA检测,出舱前进行AMS症状评分。根据AMS评分,25名评分≤10分者定为轻度AMS组,即A组;18名评分10分者定为中重度AMS组,即B组。结果与A组相比,B组进舱前CPT中收缩压升高幅度较高(P0.05);B组在模拟4500m第10hHRV中正常RR间期标准差(SDNN)、相邻
[Abstract]:Objective to investigate the role of autonomic nervous system (ans) in the pathogenesis of acute high altitude reaction (AMS). Methods 43 healthy young men were tested for 5min short range heart rate variability (HRV), cold pressure test (CPT) and plasma noradrenaline (na) concentrations before entering the cabin, and then entered the hypobaric oxygen chamber to simulate the elevation of 4500m1 days. All the subjects were subjected to HRV dynamic test at the 2nd hour of simulated altitude and then to CPT and na again. The symptoms of AMS were evaluated before leaving the cabin. According to the AMS score, 25 patients with AMS score 鈮，
