海军某大型水面舰艇舰员心率变异性分析

Analysis of heart rate variability in a naval population of a large navy surface ship

目的分析海军某大型水面舰艇舰员心率变异性(HRV)变化。方法对263名正在执行海上任务的舰员行24小时动态心电图监测(其中50名舰员任务前和任务中均行动态心电图监测),离线分析其HRV时域、频域指标,比较不同部门舰员HRV指标的差异,任务前、任务中的HRV变化,并分析舰员舰上工作时间与HRV的相关性。结果舰员任务中的HRV指标RMSSD、PNN50、HF较任务前降低(P<0.05);航空、机电、舰务、武器安全部门的部分HRV指标较医务、政工部门降低(P<0.05,P<0.01);舰务部门的三角指数较武器安全部门降低(P<0.05),机电部门的RMSSD、PNN50、三角指数、HF较武器部门降低(P<0.05);舰员的舰上工作时间与HRV的SDNN、SDANN、RMSSD、PNN50、HF、LF均呈负相关(P<0.05)。结论水面舰艇工作环境能够降低舰员的HRV,损害自主神经功能;不同部门的自主神经功能受损程度具有差异性。

AIM To analyze the changes of heart rate variability （HRV） in a naval population of a large navy surface ship. METHODS The study analyzed the heart rate variability from Hoher recording in 263 naval personnel while at sea and 50 of them also had Holter monitoring. The results were compared and the correlation of aboard work time and heart rate variability was analyzed. RESULTS RMSSD, PNNS0 and I-IF during tasks were lower than those before the task （P 〈 0. 05 ）. Some parameters of HRV in crews from the Aviation Department, Mechanical and Electrical Department, Ships Department and Weapons and Security Department were lower than those in crews of Medical and Department and Admin- istrative Department （P 〈 0. 05, P 〈 0. 01 ）. The triangular index in Ships Department was lower than that in Weapons and Security Department. RMSSD, PNNS0, HF and Triangular index in Mechanical and Electrical Department were lower than those in the Weapons and Security Department （ P 〈 0. 05 ）. The naval crews＇ aboard work time was negatively correlated with SDNN, SDANN, RMSSD, PNNS0, HF and LF （P 〈 0. 05）. CONCLUSION Working environment on surface ships reduces the crews＇ heart rate variability and effects automatic nerve function, but the degree of this changes is different when compared between different departments.
