Case reports and review of Postural Orthostatic Tachycardia syndrome (POTS)

Postural Orthostatic Tachycardia Syndrome (POTS) is a type of orthostatic intolerance that is characterized by excessive tachycardia and decreased cerebral blood flow in the upright position. This can result in significant symptoms of dizziness and light-headedness that can eventually lead to syncope. In this review, we describe two patients with POTS that varied in their degree of symptoms and treatment. One patient was able to be treated as an outpatient, while the other required hospitalization and extensive medical therapy. We would like to emphasize with this review that POTS is probably more common than it is diagnosed and is often confused with other conditions, such as chronic fatigue syndrome or functional syncope. It is important to make the correct diagnosis in order to allow appropriate treatment and to improve the quality of life for these patients.
