Kivezhdi K. Interrelation of hemodynamics' types and state of autonomous nervous system of healthy people

The thesis deals with the study of the interrelation of hemodynamics' types and the parameters of the state of autonomous nervous system in rest state and during dosed physical load. Interrelation of statistical and spectral parameters of heart rate and central hemodynamics in group of representatives of various hemodynamic types was investigated for the first time with the help of correlation analysis. The investigation of the reactions of the autonomous nervous system to the active orthostatic trial and the arithmetic test depending on the initial type of blood circulation was being held for also the first time. It was shown for the first time, that the peculiarities of the hemodynamic reactions of the representatives of the hemodynamics' types are formed not only by the correlation of sympathetic and parasympathetic parts of the autonomous nervous system in the rest state, but also, and mainly, by the reactivity of this structures and the activity of the central circuit of the heart rate regulation. The data, obtained during the work, deepen the understanding of physiological mechanisms of the adaptation reactions of the blood circulation system to different types of loads taking the state and reactivity of the autonomous nervous system into account. Normative parameters of the heart rate variability in rest and during test dosed physical loads in representatives of different hemodynamics' types are gained. They can be used in clinical and physiological investigations. The improved classification based on the blood circulation types can be used for precise diagnostics of the pre-pathological states in cardiologic patients, for selection in sports and extreme medicine. The data on the peculiarities of the changes of the autonomous nervous system under the influence of different loads in representatives of the different blood circulation types, considering its initial state, allows to conduct pre-nosological diagnostics of the people with the risk of developing of the arterial hyper- and hypotension forpreventing of these diseases using the non-medicamentosus methods.
