[Heart rhythm in students with different individual and typological characteristics of the higher nervous activity during examination stress].
The responses of the vegetative nervous system to a stress situation at the examination psycho--emotional strain were investigated on the students possessing different individual-typological characteristics of the higher nervous activity (HNA). We observed a decrease in the parasympathetic influences on the heart rate and an activation of the humoral--metabolic and sympathetic influences in all the students under exploration. It was also shown that the resistance of the students to the examination stress and the type of their vegetative reactions, to a large extent, were determined by both the individual-typological peculiarities of the HNA and the initial psychological state. The question if the vegetative supply of the mental activity at the examination stress reflects the individual-typological characteristics of the HNA has being discussed.
