| 摘 要： | 本研究模拟航天飞行中可能出现的低压缺氧、氧分压降低、吸纯氧和体力负荷几种应急条件,记录了16名男性青年的R-R间期,计算了谱质量并作频谱图。R-R间期的频谱分析可反映心脏节律的特点,而心律的变化与机体各系统机能密切相关。因此,通过它的研究对判断航天员飞行时机能状态有应用价值。

| Abstract: | Under some simulated emergencies of spaceflight conditions such as hypobaric hypoxia, breathing hypoxic oxygen, breathing pure oxygen and physical loads tests were recorded by means of R-R intervals of ECG on 16 male young subjects in the present research. Spectrograms of R-R intervals were processed and total spectral mass calculated. Analysis of heart rates by means of R-R interval spectral analysis can reflect the characteristics of cardiac rhythm. It is available for judge of the functional state of the whole body in the study of spaceflight. |
