Y1 - 2016 N1 - T2 - Tintinalli’s Emergency Medicine: A Comprehensive Study Guide, 8e AB - Syncope or fainting is a symptom complex consisting of a brief loss of consciousness associated with an inability to maintain postural tone that spontaneously resolves without medical intervention. 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 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/03/28 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1121503820 ER -
