Neurally-mediated syncope can cause exercise-induced fainting in children. A tilt table test confirmed the diagnosis in an 11-year-old boy, who improved with beta-blocker treatment.

Area of Science:

  • Pediatrics
  • Cardiology
  • Neurology

Background:

  • Exercise-induced syncope requires excluding cardiac disease, but neurally-mediated syncope is a key differential diagnosis.
  • The tilt table test is crucial for diagnosing neurally-mediated syncope.

Observation:

  • An 11-year-old boy experienced recurrent fainting during exercise.
  • Initial cardiac and neurological evaluations were unremarkable.

Findings:

  • A tilt table test with isoproterenol infusion provoked hypotension and presyncope, confirming neurally-mediated syncope.
  • Beta-blocker therapy resulted in the patient remaining asymptomatic for 10 months.

Implications:

  • This case highlights the importance of considering neurally-mediated syncope in pediatric exercise-induced fainting.
