Abstract: 

The study has involved 43 children living in areas with poor air quality due to public health indicators. In 24 % of cases during the remission the children (with bronchial asthma and recurrent bronchitis, associated with exposure to anthropogenic chemicals such as suspended solids, aromatic and oxygenated hydrocarbons, formaldehyde) demonstrated peripheral signs of obstruction and the presence of functional cardiac disorders. Being under exposure to adverse effects of environmental chemical factors, the children with chronic respiratory diseases suffer from the developing of the cardiac type of vegetative dysfunction, which was manifested in bradycardia and tachycardia, eytonic and/or sympathicotonic baseline autonomic tone, hypersympathicotonic /astimpathicotonic autonomic reactivity. In 17.9 % of the children it was manifested in transient diastolic dysfunction of right ventricle and in excessive systolic blood pressure in pulmonary artery.
