Objective: To examine a large UK cohort of patients with postural tachycardia syndrome (PoTS), to compare demographic characteristics, symptoms and treatment of PoTS at one centre compared to the largest patient group PoTS UK and to verify if their functional limitation is similar to patients with chronic fatigue syndrome (CFS).

Design: A cross-sectional study assessed the frequency of symptoms and their associated variables.

Patients And Setting: Two PoTS cohorts were: (1) recruited via PoTS UK, (2) diagnosed at Newcastle Hospitals National Health Service (NHS) Foundation Trust 2009-2012.
