Abstract
Postural orthostatic tachycardia syndrome (POTS) is a complex disorder mainly of orthostatic intolerance, often accompanied by a spectrum of symptoms related to autonomic nervous system dysfunction. Although the diagnostic criteria require an orthostatic challenge test, the associated symptom burden can be broad and is often missed by treating healthcare professionals, resulting in significant diagnostic delay. Treatment of this highly heterogenous condition is nuanced and consists of non-pharmacologic and pharmacologic approaches. Availability of POTS care is limited, with a dearth of medical specialists or general practitioners specialising in autonomic medicine. The complexity of care for those with POTS necessitates a multidisciplinary approach due to the need for extended appointment times and frequent follow-ups to monitor therapeutic response and progress. This should include a primary team consisting of a general practitioner and trained autonomic physicians with specialist nurses, allied health professionals, and any other specialists required to manage the affected systems. This state-of-the-art review aims to cover the key aspects of diagnosing and managing POTS, including special neurological, gastroenterological, psychological, and paediatric considerations. There is an urgent need to provide services that meet the needs of the growing POTS population.
