Abstract: | Recurrent episodes of sudden unexplained syncope are a common complaint of patients referred to health care professionals for evaluation. Traditional evaluations are both time consuming and expensive and leave many patients without a diagnosis. Although vasovagally mediated episodes of hypotension and bradycardia have been thought to be a common cause of unexplained syncope, this was traditionally a diagnosis of exclusion. Head-upright tilt table testing has recently emerged as a valuable method for confirming the diagnosis of vasovagal syncope and has allowed a better understanding of this phenomena. This article reviews the pathophysiology of vasovagal syncope, the use of head-upright tilt table testing in its diagnosis, and potential therapies used to prevent recurrences. |
