Approximately 2–6% of all cases of pediatric syncope can be attributed to the heart. The rare, yet life-threatening causes of syncope must be discriminated from more benign etiologies. History, physical examination findings, and electrocardiograph (ECG) findings can be used by the emergency medical practitioner to screen for patients who may be at risk for cardiac pathology. Historical “red flags” include syncope with exertion and a positive family history (Table 18–1). Cardiac causes of syncope can be divided into structural, functional, and primary electrical categories. Table 18–2 lists ECG findings associated with specific cardiac abnormalities.
