POTS is the acronym for idiopathic postural orthostatic tachycardia syndrome.  The symptoms of POTS are also observed in the conditions of depression, anxiety and panic attacks. This leads to frequent misdiagnosis.  Young women are more often affected than other ages and genders.

The symptoms of POTS may include:


Shaking or tremulousness

Increased heart rate and variable blood pressure

Fainting or near syncope




Exercise intolerance

Stomach bloating or intolerance to large meals

Alternating diarrhea and constipation

Diagnosis of POTS:

POTS is suspected when the heart rate increases by more than 30 beats per minute after standing for several minutes.  The diastolic blood pressure is also elevated.  POTS may be confirmed by motorized tilt table testing.

Treatment of POTS:

Treatment of POTS may be successful with adding salt to the diet, a medicine that prevents an increase in heart rate (propranolol), or sometimes with other medications. The medications are not a cure for the condition, they prevent the symptoms.

Prognosis of POTS:

The majority of cases of this condition resolve spontaneously within 5 years.
