An estimated one to three million Americans are affected by orthostatic intolerance, with females under age 35 the most common. Postural orthostatic tachycardia syndrome (POTS) is a disorder marked by symptoms of orthostatic intolerance within the first ten minutes of a patient moving from supine to an upright standing position. Patients must experience a sustained heart rate increase of at least 30 bpm (40 for pediatric patients) or greater than 120 bpm in the absence of orthostatic hypotension (OH). A thorough clinical evaluation should be performed prior to head-up tilt (HUT) testing to exclude other causes of tachycardia.
