Functional deviations of the cardiovascular system in children of the Aral Sea

Abstract

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.
