Prevalence of Arrhythmias and Cardiac Conduction Disorders in Young Athletes

The study goal was to assess the prevalence of arrhythmias and cardiac conduction disorders in young non-professional athletes. Nearly half of 250 athletes examined showed different ECG abnormalities. The prevalence of arrhythmias among the athletes was 54.4%. Mainly, sinus bradycardia and incomplete blockade of the right leg of the bundle of GIS were detected. Potentially dangerous ECG disorders were detected in 14.6% of the athletes. Clinically significant arrhythmias, lengthening and shortening of the QT interval, atrial fibrillation / flutter were diagnosed in 4.8% of the athletes.
