Background: Disorders of vegetative regulation in asthma relates to both adrenergic and cholinergic link. Maintenance of the vegetative balance in the development of the pathological process allows maintaining the achieved level of compensation to ensure adequate peripheral blood flow and normal bronchial tone. Objective: To assess the hyper sympathicotonic reaction in chindren with bronchial asthma. Methods: Characteristics of vegetative status in adolescents with asthma is evaluated. Further, the structure of the heart rhythm in patients with bronchial asthma depending on the initial vegetative tonus in children is characterized. Results: Patients in this group increased somewhat the share of hyper sympathetic reactive children (30,8% vs 23,1% before treatment; P__ampersandsignlt;0.05), decreased the proportion of sympathoadrenal option (7,69% vs. 23.1% to treatment; P__ampersandsignlt;0.01). Osteosynthesis the CPC remained unchanged and after treatment (7,69%; P__ampersandsigngt;0.05). Conclusion: Specific therapy of asthma has a positive effect on the performance of the COP only in boys and moderate course of the disease, and in girls and severe course of the disease is broken shifts in the levels of autonomic support of activity remained unchanged.
