Confounders of vasovagal syncope: postural tachycardia syndrome.

Cardiol Clin. 2013 Feb;31(1):101-9

Abstract

Most patients who present to a cardiologist with syncope have vasovagal (reflex) syncope. A busy syncope practice often also sees patients with postural tachycardia syndrome, often presenting with severe recurrent presyncope. Recognition of this syncope confounder might be difficult without adequate knowledge of their presentation, and this can adversely affect optimal management. Postural tachycardia syndrome can often be differentiated from vasovagal syncope by its hemodynamic pattern during tilt table test and differing clinical characteristics. This article reviews the presentation of postural tachycardia syndrome and its putative pathophysiology and presents an approach to nonpharmacologic and pharmacologic management.
