The study is devoted to the influence of disadvantages of the ecological disaster region Aral Sea on the state of the cardiovascular system in children. In 55.2% of cases, autonomic dysfunction was detected, mainly in girls of pre- and puberty age (80.8%). In 39.4% of children in the Aral Sea region hypotension was diagnosed as adaptive in 81.2% and pathological hypotension in 18.8% of cases with the initial vagotonic vegetative status according to cardiointervalography (94.6%). In children with arterial hypotension, there was a decline in the quality of life due to fatigue syndrome, cephalgia, reduced activity and deterioration of cognitive abilities. Cardiac pathology was manifested in 55.2% of cases in the form of impaired automatism of the sinus node (sinus arrhythmia, tachi and bradyarrhythmias) - 54.6%, conduction disorders (incomplete blockade of the right leg of the bundle of His) in 43.3% of cases. The identified pathology shows the need to provide comprehensive medical and social assistance to the children of the Aral Sea, along with solving environmental and economic problems of the region.
