Understanding syncope. The pathophysiology & assessment of a challenging condition that EMS crews frequently encounter.
Syncope is a transient loss of postural tone and consciousness following which, by definition, the patient has a spontaneous recovery without intervention. The differential diagnosis of syncope is broad and spans benign to life-threatening conditions. Identifying and treating serious conditions that may mimic syncope and identifying patients at high risk (cardiac syncope) are challenges that face prehospital providers. A comprehensive history and physical provide the most useful information in making these distinctions. Syncope is a symptom, not a disease; therefore, treatment must be targeted to the underlying disease process.
