Syncope, and pre-syncope with observed convulsions are very common and frequently investigated in the emergency department. Typical syncope with a normal examination requires minimal investigation. Neuroimaging and EEG will not help in determining the etiology or management of patients with typical syncope in the absence of focal neurologic symptoms or findings on examination.
