title: [Possible systems approach to the study of circulatory system regulation in schizophrenia].
abstract: From the point of view of a systemic approach the model of schizophrenia is considered as a system of 2 substructures: clinico-psychopathological and vegetative-regulatory. Changes in the latter are shown by disturbances in the circulation control in orthostasis. Factor analysis of the respective indices in 70 cases of schizophrenia established a correlation between the factor of progression and the quality of palpitation frequency regulation. The character of correlations of these indices with the indices of regulation permits one to distinguish the forms of development in schizophrenia. Conclusions about a relationship between clinical and regulatory substructures in the model of schizophrenia are confirmed by a discriminant analysis of the respective data on 122 mental patients.
