Post Orthostatic Tachycardia Syndrome (POTS)

Satisfactory Essays

Post orthostatic tachycardia syndrome (POTS) is an autonomic disorder characterized by orthostatic intolerance, such as, light headiness, fatigue, sweating, tremor, anxiety, exercise intolerance, and fluctuation in blood pressure in either direction. A person with POTS will experience heart rates that increase 30 beats or more per minute upon standing and/or increase to 120 beats or more per minute upon standing (Grubb, 2000). These exaggerated heart rate increases usually occur within 10 minutes of rising. These symptoms of POTS may lead patient limitation of activity; for example, chronic debilitating disorders, prolonged bed rest, or medication that impair autonomic function that may have to be excluded (Agarwal, Garg, Ritch, Sarkar, 2007).
