Syncope
Introduction
Syncopeis a sudden, brief loss of consciousness with loss of postural tone followed by spontaneous revival. The patient is motionless and limp and usually has cool extremities, a weak pulse, and shallow breathing. Sometimes brief involuntary muscle jerks occur, resembling a seizure. Near-syncopeis light-headedness and a sense of an impending faint without loss of consciousness. It is usually classified and discussed with syncope because the causes are the same. Seizure Disorders None Diagnosis depends on a careful history, eyewitness accounts, or fortuitous examination during the event.
