Autonomic syncope in pediatrics: A practice-oriented approach to classification, pathophysiology, diagnosis, and management

This paper presents a practice-oriented approach to the problem of syncope in pediatrics. Autonomic syncope is the major etiologic category in pediatrics and consists of 2 types: reflex and dysautonomic. The latter type is rare in pediatrics. Reflex syncope has 4 subtypes: neurocardiogenic, central, situational, and cerebral. Neurocardiogenic syncope, the most common subtype, is easily diagnosed by taking a careful, detailed history; identifying diagnostic red flags; performing a complete physical examination; and ordering a minimum of laboratory tests. Patient and parent education is essential, and usually, without medication, outcomes are good.
