Abstract

Abstract: Background: Postural Orthostatic Tachycardia Syndrome (POTS) is a dysautonomia of unclear etiology. POTS is defined as a form of orthostatic intolerance characterized by an increase in heart rate ≥ 30 bpm or to a heart rate ≥120 bpm upon standing. The clinical manifestations include dizziness, palpitations fatigue, anxiety, nausea and fainting. There is a paucity of data available on adult population. This study aims to identify and evaluate demographic features of adult patients with POTS in a large tertiary specialty clinic. Methods: 447 patients diagnosed with POTS between 8/21/2018 and 8/20/2019 were randomly selected from our electronic records, and clinical data obtained during initial outpatient evaluation was reviewed retrospectively for race, gender and age. Results: Out of 447 patients, 407 (91%) are female and 40 (9%) are male. Amongst them, 417 (93%) patients are White Caucasian of which 381 (91%) are female and 36 (9%) are male; 12 (3%) are Black/African-American of which 11 (92%) are female and 1 (8%) is male; 10 (2%) are Hispanic of which 100% are females; 4 (1%) are Asian of which 2 (50%) are females and 2 (50%) are males and 4 from other races of which 3 (75%) were female and 1 (25%) was male. Patients had a mean age of 32.9 with a standard deviation of 11.96. Conclusions: POTS predominates in females, middle age population, and may be heavily prevalent in White Caucasians. Key messages: Further clinical studies on more geographically spread populations are encouraged to support our findings on racial prevalen
