electrical disease. During preparticipation screening that includes the use of ECG, asymptomatic athletes with any of these abnormal findings should undergo additional testing. Athletes presenting with symptoms (ie, palpitations, exercise, or emotion related syncope or seizure-like activity) should undergo prompt evaluation including an ECG. The evaluation of an athlete with abnormal ECG findings is conducted ideally in consultation with a cardiovascular specialist familiar with primary electrical diseases and with experience caring for athletes.
