title: [Conceptual approaches to the diagnosis of stress-induced functional disorders in humans under conditions of industrial activity].
abstract: In accordance with the fundamental concept of the systems symmetrical approach, a model of the body's "ideal functional status" and a polyparametric method for diagnosing the human functional status (the method has been patented in Russia) were developed, on the basis of the unified set of amplitude and time parameters of a complex of physiological parameters (ECG, etc.). The systems symmetrical approach is basically new in defining the ratio of harmonic parameters acting as new diagnostic evidence for the health status. The unchanging ratio of parameters of autovariation processes in the cardiac, vascular, and respiratory systems, their changes in the development of the adaptative syndrome and the value were examined in healthy individuals at rest and during exercise an intensive productive activity (point brazing at a plant of electron devices), and in the trainees. It was demonstrated that the mechanism of development of adaptative processes was associated with the synchronization of autovariations in the cardiorespiratory and vascular systems and the involution of adaptative processes, their break, depletion, i.e. stress, were determined by the imbalance of relationships and the desynchronization of autovariations in these systems. To define a set of cardiorespiratory and hemodynamic parameters is necessary, but insufficient to evaluate (diagnose) the health status and health-disease intermediate diseases (stress and adaptative overtension). The ratio harmonicity of these parameters, i.e. well-balanced relations between the subsystems is the main characteristic. The assessment of the human health status in terms of the reference-the model of the ideal status as the ideal health status without using the complex and indefinite concept of the normal and moderate health status-is conceptual for polyparametric status estimation.
