Exercise-induced vasodepressor syncope in a collegiate wrestler: a case study.
OBJECTIVE
To present the case of an 18-year-old collegiate wrestler diagnosed with vasodepressor syncope.


BACKGROUND
Vasodepressor syncope and the pathophysiologic mechanisms responsible are not fully understood. It is postulated that a sudden, rapid reduction in venous return to the heart allows for quite forceful ventricular contractions. Hypotension, bradycardia, and possible cerebral hypoxia may result, which could cause loss of consciousness.


METHODS
Cardiovascular, neurologic, metabolic, and psychogenic causes.


METHODS
Pharmacologic therapy of fludrocortisone acetate and potassium chloride was effective. The athlete returned to full activity without restrictions and remained symptom free throughout the remainder of the season.


RESULTS
Vasodepressor syncope is usually associated with full syncope. However, this 18-year-old wrestler never fully lost consciousness. His symptoms occurred primarily with exercise.


CONCLUSIONS
The athletic trainer should consider exercise- induced vasodepressor syncope as a possible etiology for those athletes who present with presyncopal episodes.
