【摘要】：目的探讨常规潜艇水下状态对人体24h动态心电图窦性心率和心率变异性的影响。方法自2002年3月-2009年7月纳入124名常规潜艇水下航行状态的艇员作为水下组,另选118名陆勤战士作为陆上组(对照组),均为男性。采用12导联动态心电图检查分析系统,对常规潜艇水下状态的艇员进行连续24h动态心电图监测,记录24h平均心率、工作时平均心率及最高心率、睡眠时平均心率和最低心率,并分析水下组与陆上组心率变异性指标的差异。结果与陆上组相比,水下组睡眠时平均心率及最低心率明显加快(P0.01),但24h平均心率,工作时最高心率及平均心率均无明显差异。24h心率变异性比较,水下组相邻R-R间期差值的均方根值(rMSSD)、正常相邻R-R间期差值50ms的百分比(PNN50)较陆上组显著下降(P0.05)。而两组24h全部窦性心搏R-R间期标准差(SDNN)、24h每5min时段平均间期标准差(SDANN)、相邻R-R间期之间的标准差(SDSD)、三角函数无明显差异。结论常规潜艇水下工作状态对艇员睡眠时的心血管自主神经有明显影响。
[Abstract]:Objective to investigate the effect of underwater state of conventional submarine on sinus heart rate and heart rate variability of human body 24 h dynamic electrocardiogram. Methods from March 2002 to July 2009, 124 submariners were included as underwater group. Another 118 land soldiers were selected as land group (control group, all male). Using 12-lead dynamic electrocardiogram examination and analysis system, continuous 24-hour dynamic electrocardiogram monitoring was used to record the mean heart rate in 24 hours. The mean heart rate and maximum heart rate at work and the mean heart rate and minimum heart rate in sleep were analyzed, and the differences of heart rate variability between underwater group and land group were analyzed. In the underwater group, the mean heart rate and the lowest heart rate were significantly increased during sleep, but there was no significant difference in the mean 24 h heart rate, the maximum heart rate and the average heart rate at work. The root mean square value of RR-R interval difference in underwater group and the percentage of normal adjacent R-R interval difference of 50ms in underwater group were significantly lower than those in land group (P 0.05), while the R-R interval standard deviation of all sinus beats in both groups at 24 h was different from that in normal group (SDANNN), and the phase of SDANNN was also observed in the two groups (P < 0.05), but the mean deviation of R-R interval in all sinus beats of the two groups at 24 h was higher than that in the control group (P < 0.05). There was no significant difference in the standard deviation between R-R intervals and trigonometric functions. Conclusion the underwater working state of conventional submarine has a significant effect on cardiovascular autonomic nervous system during sleep.
