Syncope accounts for approximately 1% to 2% of ED visits each year and up to 6% of hospital admissions.1,2,3 In the Framingham Heart Study, 7814 patients were followed for 17 years, and 10.5% reported syncope.4 Syncope in the preceding year is the best predictor of recurrence.5 It can affect the young and the old, with the elderly having the greatest morbidity.6Near-syncope, a premonition of fainting without loss of consciousness, shares the same basic pathophysiologic process as syncope and may carry the same risks.7,8
