58 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. Stress¬ful physical activity in children with polymorbidity leads to the development of ventricular extrasystole (VE) much earlier. It has been estab¬lished that in these athletes, a decrease in energy supply often precedes the development of cardiac arrhythmias, in particular VE.
