Abstract

Syncope is defined as transient loss of consciousness associated with the loss of postural tone that is a result of sudden transient and inadequate cerebral blood flow; an acute fall in systolic blood pressure to less than 70 mmHg causes an interruption of cerebral blood flow for more than 8 seconds. Syncope is a common problem representing up to 1% of medical admissions to general hospitals and 3 to 7% of all U.S. emergency room visits.
