大多数心脏病专家诊断为晕厥的患者为血管迷走神经性晕厥。一个忙碌的晕厥实践也经常看到患者姿势性心动过速综合征，往往表现为严重的复发性晕厥前期。在没有充分了解其表现的情况下，可能很难识别这种晕厥混杂因素，这可能会对最佳管理产生不利影响。体位性心动过速综合征通常可通过倾斜试验中的血流动力学模式和不同的临床特征与血管迷走性晕厥相鉴别。本文综述了体位性心动过速综合征的表现及其假定的病理生理学，并提出了非药物和药物治疗的方法。
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.
