A person with POTS experiences an increased heart rate with little change to his blood pressure when he is standing, according to the Rare Diseases Clinical Research Network. The increased heart rate may demonstrate that a person's cardiovascular system is working to maintain blood flow to the brain and blood pressure. Individuals with POTS may experience an unusual decline in blood plasma volume, known as hypovolemia, which may be due to blood pooling in the legs and abdomen.

Women under the age of 35 are the most common sufferers of POTS, states the Rare Diseases Clinical Research Network. The cause of POTS is unknown, and in some cases, patients experience a viral infection before the onset of POTS symptoms. Since the severity of POTS changes and it is referred to by varying names, many patients with POTS never receive a diagnosis. The symptoms of POTS are similar to those of other conditions, such as chronic fatigue syndrome, physical deconditioning, and neurally mediated syncope, which also makes diagnosis difficult.

POTS treatments regulate circulatory issues or alleviate low blood pressure, reports the Rare Diseases Clinical Research Network. Treatments for POTS include medication therapy, drinking water, ingesting salt or fludrocortisones, and engaging in orthostatic exercise.
