RISK FACTORS FOR SOME CARDIAC ARRHYTHMIAS IN CHILDREN ENGAGED IN GYMNASTICS

Аннотация

Sports loads predispose to the development of changes in autonomic regulation associated with metabolic disorders in the myocardium and, with prolonged exposure, can contribute to the formation of various extrasystolic arrhythmias. 60 girls of 7-8 years old were selected, who underwent a routine preventive examination before gymnastics, which included: a clinical examination, as well as: ECG, Echo-CG, Holter-ECG, heart rate variability. The analysis of the influence of factors suggests that heart rhythm disturbances in young athletes are primarily associated with physical activity, in combination with comorbid pathology. Stressful physical activity in children with polymorbidity leads to the development of ventricular extrasystole (VE) much earlier. It has been established that in these athletes, a decrease in energy supply often precedes the development of cardiac arrhythmias, in particular VE.
