Evaluation of the systemic involving of the connective tissue (SICT) under the new Ghent nosology (2010) showed that in children with isolated ACLV born to parents exposed to the Chernobyl disaster, its expression is associated with their location and quantity. The degree of systemic involvement of connective tissue is confirmed by the results of the analysis of features echostructure of isolated ACLV (the presence of thickening and calcification), echomorphometry, assessment of systolic (hypokinetic organization of the central hemodynamics), and the relaxation functions of the heart (initiation of diastolic dysfunction). High level of SICT (score greater than 5) indicates systemic damage to the body and particularly the heart, which requires dynamic monitoring and preventive measures.

156 children of the main group (were born to parents irradiated in the result of Chernobyl disaster), in which according to Doppler echocardiography isolated abnormal chords of the left ventricle (AHLV) identified, 44 children of control group and 50 children of referent group were involved in the study Analysis of indicators of operational regulation of heart rate in children of primary group indicate the existence of autonomic dysregulation, which has the maximum expression in children with a threshold number of isolated abnormal chords. Evidence of autonomic dysregulation in children born to parents irradiated in the result of the Chernobyl disaster with isolated AHLV requires primary and secondary prevention to reduce the frequency of unfavourable clinical course.
