title: [State of autonomic regulation mechanisms in arterial hypotension].
abstract: To investigate the role of suprasegmental and segmental parts of autonomic nervous systems (ANS) in genesis of arterial hypotension (AH) 75 individuals with arterial hypotension as well as 30 healthy persons were examined using clinical and psychological methods, evaluation of the state of ANS segmental part by means of evoked skin sympathetic potentials, spectral analysis of the variability of the heart rhythm, 5 standard cardiovascular tests according to Ewing. The conclusion was made that individuals with AH had combination of alterations of both emotional-personality sphere and autonomic functions in all systems of organism tested. Exactly they had psychoautonomic syndrome presenting as combination of asthenic manifestations, elements of Reynaud phenomenon and headaches pronounced differently (headaches of tension more frequently). Clinical alterations were combined with changes of indices of functional testing, that reflected disorders in some link of sympathetic regulation including baroreflex one. Decompensation in individuals with AH and change for the worse of the indices of functional testing were due both to the increase of psychoautonomic disorders, growing of desintegrational processes in ANS and the decrease of adaptive mechanisms in its sympathetic part.
