Postural orthostatic tachycardia syndrome (POTS) is a condition in which a change from a supine to an upright position causes an abnormally large increase in heart rate which may be accompanied by a variety of physical complaints. We report two cases illustrating the heterogeneity of this syndrome. We give an update on the etiology of POTS, which is still poorly understood, and its overlap with other syndromes such as chronic fatigue syndrome. Clinicians should be aware of POTS, a fairly common clinical entity, that can result in significant impairments to a patient's quality of life. Lifestyle measures (under which adequate fluid and salt intake, exercise) are a first line of treatment; if insufficient, pharmacotherapy can be considered to improve quality of life.
体位性直立性心动过速综合征（POTS）是一种从仰卧位变为直立位时会导致心率异常大幅增加，并可能伴有多种身体不适症状的疾病。我们报告两例病例以说明该综合征的异质性。我们对POTS的病因进行了更新，其病因仍知之甚少，以及它与慢性疲劳综合征等其他综合征的重叠情况。临床医生应了解POTS，这是一种相当常见的临床病症，可对患者的生活质量造成严重损害。生活方式措施（包括充足的液体和盐分摄入、运动）是一线治疗方法；如果效果不佳，可考虑药物治疗以改善生活质量。
