The article presents the results of clinical and instrumental examination of adolescents and young men of military age with bradyarrhythmia. The study involved 2067 people (mean age19,7 ± 2,7 years), subject to conscription (from 17 to 27 years) and potential conscripts (16-year-olds). According to the results of the screening ECG, bradyarrhythmia (sinus bradycardia, sinus bradyarrhythmia, rhythm and conduction disorders) was diagnosed in 630 adolescents and young men of military age. We studied the functional status of the autonomic nervous system on the device “Cardiometry-MT” (Russia). The functional state of the autonomic nervous system was studied on the basis of cardiointervalography and correlation rhythmography. Evaluation of the functional state of the autonomic nervous system was carried out according to three parameters: the type of vegetative regulation of the heart rhythm (normotonic, vagotonic, sympathicotonic); reactivity of the sympathetic and parasympathetic parts of the autonomic nervous system (normal reactivity, hyperreactivity, low reactivity, and paradoxical reactions); nature of vegetative maintenance of cardiac activity (normal vegetative maintenance of cardiac activity, vegetative maintenance with adaptation, vegetative maintenance with disadaptation). According to the results of respiratory samples from 81,9% of adolescents and young men of military age with bradyarrhythmia diagnosed neurocirculatory asthenia, of whom 63,6% – light, while 18,3% – severe degree. With a mild form of neurocirculatory asthenia, compensatory mechanisms are connected, so vegetative homeostasis is not generally disturbed and the heart rhythm responds adequately to the effect of physiological stimuli. Severe form of neurocirculatory asthenia is characte rized by disadaptation of vegetative maintenance of cardiac activity. Such patients need regular follow-up because they are at risk for developing cardiovascular diseases.
