Syncope: A tough pill to swallow.

Syncope is a common clinical syndrome that is typified by loss of consciousness and has several etiologies ranging from benign to potentially life-threatening. To differentiate syncope from other conditions, a detailed history is crucial. Several key historical components that aid in establishing the etiology of syncope include frequency, identifiable triggers, and prodromal symptoms. The differential diagnosis of syncope includes mechanical fall, seizure, narcolepsy, intoxication, and psychiatric conditions. Meticulous review of a patient's past medical conditions and medication list must be completed when evaluating syncope etiologies, as this information may aid in the elucidation of a cause or contributing factor. This case report illustrates the importance of history collection, as the underlying cause of syncope is not always easily identified.
