Pediatric Syncope: High-Risk Conditions and Reasonable Approach.

Syncope is a common presentation to the emergency room.

The primary purpose of evaluation of the patient with syncope is to determine whether the patient is at increased risk for death and needs either admission to the hospital or an expedited outpatient evaluation. This article reviews some of the most dangerous causes of syncope in the pediatric patient.
