title: Cerebral syncope in children.
abstract: We report a child with recurrent syncopal episodes who underwent head-up tilt testing according to a protocol that includes continuous and noninvasive measurement of brain oxygen saturation. We demonstrated significant cerebral hypoxemia during syncope without concomitant systemic hemodynamic disturbances. This response to head-up tilt test suggested the diagnosis of cerebral syncope.
