Orthostatic testing may yield more abnormalities than electrophysiologic testing in pediatric syncope; leaves open need for prospective validation before practice change.
Does orthostatic testing provide a higher diagnostic yield than electrophysiologic testing in children and adolescents with unexplained syncope?
Orthostatic testing has a higher positive diagnostic yield than electrophysiologic testing for unexplained syncope in pediatric patients and should be considered early in their cardiovascular evaluation.
