Postural orthostatic tachycardia syndrome (POTS) is an often-disabling syndrome of symptomatic orthostatic tachycardia in the absence of orthostatic hypotension. POTS has been associated with a wide variety of conditions, including diabetes, some autoimmune disorders, infections, trauma, surgery, stress, mastocytosis, and the hypermobility type of Ehlers-Danlos syndrome. Palpitations, dizziness, and other symptoms of POTS occur mainly when standing upright and are typically relieved by sitting or lying flat.
