Postural Tachycardia Syndrome

Postural Tachycardia Syndrome (PoTS), previously known as Postural Orthostatic Tachycardia Syndrome (POTs) is increasingly recognised as an important manifestation of dysautonomia. The autonomic system controls many aspects of bodily function including cardiovascular function, bowel function, bladder function, sweating, vision, cognition, etc..

 

Postural Tachycardia Syndrome is diagnosed when the heart rate increases by more than 30 bpm (40 bpm in children) within 10 minutes of standing or tilting without any associated drop in blood pressure. 80% of sufferers are female.
