title: [Exercise-induced syncope].
abstract: When faced with a patient with exercise-induced syncope, it is important to exclude heart disease. Nevertheless, neurally-mediated syncopes should be taken into account in the differential diagnosis and the tilt table test is essential to establish this diagnosis. We report the case of an 11-year-old boy, who presented recurrent exercise-induced fainting. The results of cardiac and neurologic tests were negative. The tilt table test with pharmacological challenge with isoproterenol infusion induced arterial hypotension and presyncope, and a diagnosis of neurally-mediated syncope was made. After initiating beta-blocker treatment, the patient has remained asymptomatic during a follow-up of 10 months.
