The hallmark symptom of POTS is an increase in heart rate from sitting to an upright position of more than 30 beats per minute or to a heart rate greater than 120 beats per minute within 10 minutes of being upright.

To be given a diagnosis of POTS, a person needs to have: 



  • A sustained increase in heart rate of greater than 30 beats per minute within 10 minutes of standing.
  • The heart rate increase is often over 120 beats per minute when upright.
  • Those aged 12-19 years require an increase of at least 40 beats per minute. 
  • Some patients with POTS also have low blood pressure.

Patients are usually diagnosed by a tilt table test.
