Intensive, prolonged training may slightly increase the size of the ventricles and thicken their walls. An ECG may show sinus bradycardia, increased QRS voltage, early repolarisation and T wave changes. Changes due to athlete’s heart are always asymptomatic and will reverse during a training-free period. Symptoms suggesting heart disease are an indication for further investigations.
