Syncope

  • Noble O. Fowler

Abstract

Syncope may be defined as a sudden transient loss of consciousness that usually results from a decrease in cerebral blood flow. Often syncope occurs in people previously in relatively good health. In this discussion, syncope is differentiated from other causes of unconsciousness, such as grand mal epilepsy or hypoglycemia. Syncope further does not refer to shock states associated with burns, septicemia, blood loss, trauma, or myocardial infarction. It does not refer to coma, which is more prolonged and usually associated with brain damage, drug toxicity, diabetic keto-acidosis, uremic states, and the like. The problem of syncope was recently reviewed (Manolis et al., 1990). Syncope was found to account for 3% of emergency room visits and 6% of medical admissions to a general hospital.
