SPECTRAL ANALYSIS OF R-R INTERVALS UNDER SOME SIMULATED EMERGENCIES OF SPACEFLIGHT

Abstract

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.
