转场部队飞行员心率变异性分析

Analysis of Heart Rate Variability of Military Pilots Transferring to Another Airport

目的研究分析转场部队飞行员心率变异性状况。方法随机选取转场及驻场部队飞行员各36名,连续记录2 h心电信号,检测分析心率变异性。结果转场部队飞行员心率变异性的异常率(94.4%)明显高于驻场部队飞行员(63.9%),P<0.01;转场部队飞行员的R-R间期标准差、相邻R-R间期谱的方根值、总功率、低频、高频较驻场部队飞行员均明显低(P<0.01),转场部队飞行员的低频与高频比较驻场部队飞行员明显偏高(P<0.05)。结论转场部队飞行员心率变异性明显降低,应进行有效干预。

Objective To investigate the heart rate variability （HRV） of military pilots transferring to another airport. Methods Thirty-six military pilots who had transferred to another airport （ Group I ） and another thirty-six military pilots who stayed put （ Group 2） were randomly selected. ECG of both groups was recorded for two consecutive hours to measure and analyze their heart rate variability. Results The rate of HRV abnormity of pilots in Group 1 was significantly higher than that in Group 2 （P〈0.01）. SDNN , rMSSD, TP, LF, HF of pilots in Group 1 were all significantly lower than those in Group 2 （P〈0.01）, but the LF/HF of pilots in Group 1 was significantly higher than that of Group 2 （P〈0.05）. Conclusion The heart rate variability of military pilots transferring to another airport can be decreased significantly. Some effective measures should be taken to solve this problem.
