    Background: The postural tachycardia syndrome (POTS) is a condition of the autonomic nervous system with symptoms of orthostatic intolerance. In POTS patients, orthostatic stress leads to an overshoot of heart rate increase without a fall in blood pressure. The purpose of this study is to distinguish between anxiety disorders and anxiety as a concomitant phenomenon of orthostatic stress.

    Methods: 50 patients fulfilling the diagnostic criteria (orthostatic symptoms, heart rate increase of > 30 bpm or up to > 120 bpm by testing with tilt-table) were included. The study design included a thorough medical history as well as standardised questionnaires about anxiety.

    Results: The average heart rate increase was 36 bpm after ten minutes of standing and 42 bpm after maximal standing time (max. 45 minutes). POTS patients scored significantly higher than a comparison group in a range of anxiety disorders by using anxiety questionnaires like "Beck Angst-Inventar" (BAI) and trait test of "State-Traits-Angstinventar" which include autonomic items. When questionnaires were used that exclude autonomic items (anxiety sensitivity index: ASI; Interaktions-Angst-Fragebogen: IAF) there was no difference.

    Conclusion: POTS patients do not exhibit signals of anxiety disorders more often than control groups, provided that questionnaires without autonomic items are used.

    Great to see a study that recognises many psychological questionnaires confound physical and psychological issues, and that questionnaires that do not give false positives for psychological issues in people with physical conditions are needed.
