Syncope is defined as a sudden transient loss of consciousness accompanied by loss of postural tone with spontaneous recovery that does not require resuscitative interventions. Although syncope occurs in adults of all ages, older adults are particularly vulnerable to syncope.<sup>58 Kapoor W.N. Evaluation of syncope in the elderly J Am Geriatr Soc 1987 ;  35 : 826

In this population, recurrent syncope is associated with accelerated functional decline. As the U.S. population grows older, syncope is becoming increasingly important as a major cause of morbidity and medical resource utilization.
