[Biochemical factors in the pathogenesis of autonomic crises].
Twenty-six neurotic patients with psychovegetative syndromes and eight healthy subjects were studied for the following vegetative and biological parameters: heart rate, respiration rate, skin galvanic reflex (SGR), and blood levels of lactic acid (LA) and pyruvic acid (PA). The examination was carried out under normal conditions and after exercise. It was found that the patients were more reactive to exercise as compared to the healthy subjects with regard to both vegetative (respiration rate, heart rate) and biochemical parameters (LA, PA). The maximal reactivity was observed to be associated with a considerable degree of emotional stress revealed by the test of comprehensive study of personality.
