Key result
A methodology and microprocessor information system were developed to objectively assess emotional stress by calculating cross-correlation coefficients between vital autonomic parameters.
A microprocessor system analyzing the cross-correlation of heart and respiratory rhythms may provide an objective method for real-time monitoring of emotional stress during wakefulness and sleep.
New biosensor approaches for autonomic stress monitoring require prospective validation; leaves open clinical thresholds for dangerous emotional stress.
Modern medical, biological and psychophysiological studies convincingly show emotional stress is the cause of many psychosomatic disorders, exerts a comprehensive destructive influence on the vital activity of an organism, undermines the health of people, reduces the reliability of human activity.Therefore, it is extremely important to control the degree of emotional stress development (its autonomic features) and to determine that dangerous border beyond which one can not go out.However, with all the significance and widespread prevalence of stress among the population, there are still no methods of measuring stress in people in real everyday life; full-fledged objective criteria of stress are not developed.The aim of the research is to develop an information system for everyday, objective self-control of stress level, with the help of which it would be possible to preserve health of stressed people.On the basis of our experimental studies, an objective criterion of emotional stress, based on the calculation of cross-correlation coefficients between vital autonomic parameters: heart rate, respiratory rate and blood pressure, is proposed.It was found emotional stress is characterized by a decrease in cross-correlation between autonomic parameters, a disorder of biorhythms, due to the disintegration of the activity of functional systems.The methodology and information system for an objective assessment of emotional stress, which can be recommended for the building up of a specialized microprocessor system designed for comprehensive, rapid assessment of emotional stress level in sleep and wakefulness and prevention of disorders of vital functions, is developed.

О. С. Глазачев (2017) studied Emotional stress. Microprocessor device for cross-correlation analysis of cardiac and respiratory rhythms was evaluated on Cross-correlation coefficients between heart rate, respiratory rate, and blood pressure. A methodology and microprocessor information system were developed to objectively assess emotional stress by calculating cross-correlation coefficients between vital autonomic parameters.
