Exercise-related syncope in the young athlete: reassurance, restriction or referral?

Abstract

A common event in young adults, syncope is usually benign and only rarely requires more than simple reassurance. However, exercise-related syncope always requires investigation because it may be the only symptom that precedes a sudden cardiac death. Syncope that occurs during exercise tends to be more ominous than that occurring in the postexertional state. During the physical examination, the cardiovascular system should be evaluated carefully. An electrocardiogram is mandatory and requires close scrutiny, with further testing ordered as indicated. The investigation of syncope should specifically exclude known pathologic diagnoses before a complete return to activity is permitted. In cases where a diagnosis is not clearly established, consultation or referral may be warranted.
