中国健康飞行员心率变异性指标分析

Analysis of Heart Rate Variability in Chinese Healthy Pilot.

为探讨不同年龄、不同性别的健康飞行员２４ｈ心率变异性（ＨＲＶ）正常值范围、指标特征和ＨＲＶ分析在飞行员健康鉴定中的应用价值，对１１８名健康男女飞行员、健康地勤人员进行连续２４ｈ心率监测和分析，结果：ＳＤＮＮ、ＨＲＶｉ、ＲＭＳＳＤ、ＨＦ、ＴＰ女飞行员均明显高于男飞行员。ＲＭＳＳＤ、ＨＦ、ＴＰ男飞行员组明显低于地勤对照组；男女飞行员按不同年龄分组进行ＨＲＶ值比较分析，发现男飞行员组ＳＤＮＮＡ组明显大于Ｂ、Ｃ组，ＨＲＶｉ在Ｂ组则明显小于Ｃ组（Ｐ＜０．０１）。女飞行员组中，ＲＭＳＳＤ、ＨＦ和ＴＰ三项指标Ｃ组明显大于Ａ和Ｂ组（Ｐ＜０．０１）。结论：健康男、女飞行员之间ＨＲＶ多项指标有明显差异；尤其是反映迷走神经活性的指标明显大于男性。飞行员ＨＲＶ具有明显的年龄特征。

Normal range of 24 h heart rate variability (HRV) and its application in healthy pilots of different age and sex were investigated.24 h HRV data in 118 healthy male and female pilots and ground crew were measured.Comparing with male pilots,SDNN,HRV i,RMSSD,HF and ATP values in females are obviously higher (P<0.05),.For HRV comparison analysis,the pilots were divided into three age groups.The results show that SDNN value of male pilots in group A is obviously higher than those in group B and C(P<0.01).In female pilot group,the RMSSD,HF and ATP values of group C,are obviously higher than those of A and B (P<0.01).It demonstrats that many HRV parameters show significant difference between male and female pilots,the HRV parameters in female pilot are obviously higher than those in males,especially for such parameters which reflect vagal nerve activity.Age factor effect is apparent in pilot's HRV data.Some HRV parameters in different age groups show significant difference.Most 24 h HRV parameters in pilots flying different types of aircraft show no significant difference.
