POTS is often accompanied by common features of orthostatic intolerance-in which symptoms that develop while upright are relieved by reclining. For people between ages 12 and 19, the minimum increase for a POTS diagnosis is 40 beats per minute. The resulting heart rate is typically more than 120 beats per minute. In adults, the primary manifestation is an increase in heart rate of more than 30 beats per minute within ten minutes of standing up. Person standing and measuring heart rate with a pulse oximeter which shows tachycardia of 108 bpm The average age for POTS onset is 20 years old, and it occurs about five times more frequently in females than in males. It is estimated that 500,000 people in the United States have POTS.

Retrospective studies has shown that five years after diagnosis, 19% of patients had a full resolution of symptoms. About 80% of patients have symptomatic improvement with treatment, while 25 percent of patients are so disabled they are unable to work. More than 50% of patients whose condition was triggered by a viral infection get better within five years. Medications used may include beta blockers, pyridostigmine, midodrine or fludrocortisone. Treatment may include avoiding factors that bring on symptoms, increasing dietary salt and water, small and frequent meals, avoidance of immobilization, wearing compression stockings, and taking medications. Other conditions which can cause similar symptoms, such as dehydration, orthostatic hypotension, heart problems, adrenal insufficiency, epilepsy, and Parkinson's disease, must not be present.
Prolonged bedrest may lead to multiple symptoms, including blood volume loss and postural tachycardia. A spinal fluid leak (called spontaneous intracranial hypotension) may have the same signs and symptoms as POTS and should be excluded. This increased heart rate should occur in the absence of orthostatic hypotension (>20 mm Hg drop in systolic blood pressure) to be considered POTS. A POTS diagnosis in adults is characterized by an increased heart rate of 30 beats per minute within ten minutes of standing up, while accompanied by symptoms. Risk factors include a family history of the condition. It has been shown to emerge in previously healthy patients after COVID-19. POTS may develop after a viral infection, surgery, trauma or pregnancy. POTS symptoms may be treated with lifestyle changes such as increasing fluid and salt intake, wearing compression stockings, gentler and slow postural changes, avoiding prolonged bedrest, medication and physical therapy. Other conditions associated with POTS include Ehlers–Danlos syndrome, mast cell activation syndrome, irritable bowel syndrome, insomnia, chronic headaches, chronic fatigue syndrome, and fibromyalgia. Symptoms may include lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea, diminished concentration, tremulousness (shaking), syncope (fainting), coldness or pain in the extremities, chest pain and shortness of breath. Postural orthostatic tachycardia syndrome ( POTS) is a condition characterized by an abnormally large increase in heart rate upon standing.
