Reproducibility of oscillation characteristics of heart rate and stroke volume in men
Introduction. To apply practically and to interpret theoretically the results obtained using different methods of evaluating the physiological hemodynamic oscillations, it is highly important to what extent the values of indicators are measured according to them after a long period of time.
Purpose. The purpose of our work was to research the reproducibility of the indicators of oscillation wave structure of heart rate (HR), stroke volume of blood (SV) and the level of their synchronization.
Methods. The repeated measurements of the indicators of spectral analysis of HR oscillations and SV were conducted on 37 men in 216 days on average.
Results. The indicators of spectral analysis of stroke volume and the duration of RR interval at rest and with different load remain relatively stable during rather long period of time. The cross-spectral power of stroke volume oscillations and the duration of RR interval in the range of 0.05-0.15 Hz is rather stable individual characteristics of cardio-vascular system of a man.
Originality. The reproducibility of the characteristics of spectral analysis of HR and SV oscillations in men after a long period of time is presented for the first time.Conclusion. The characteristics of the oscillations of heart rate and stroke volume are the stable individual characteristics of the activity of cardio-vascular system of a man.
