96 adolescents with functional cardiopathy were inspected. All children underwent clinical, laboratory, and instrumental examination. In all patients, the initial autonomic tone was assessed using a questionnaire, and autonomic reactivity was assessed using cardiac rhythmography. It was found that dysfunction of the autonomic nervous system is involved in the pathogenesis of functional cardiopathy, which determines the clinical symptoms in these patients, and autonomic disorders in the group of female adolescents are more significant than in male adolescents. Cardiorhythmography quite accurately reveals the imbalance of the body's adaptive resources for physical and mental stress, in this regard, it can be used to determine risk groups for the formation of cardiovascular pathology.
