Head-upright tilt table testing in children with unexplained syncope.

Recurrent syncope in the young patient can be an anxiety-provoking experience that is often difficult to diagnose. Head-upright tilt table testing has emerged as a method for provoking episodes of vasodepressor syncope in predisposed individuals and thereby establishing a diagnosis. Currently indicated in the evaluation of young patients with recurrent unexplained syncope, it has also proven useful in differentiating convulsive syncope from epilepsy. Further studies will be needed to better define its role in the evaluation and management of recurrent syncope in children and adolescents.
