Diagnosing Postural Orthostatic Tachycardia Syndrome
The tilt table test is the preferred approach in testing for POTS. During this test, the individual will lie down on a table and then be strapped down for stabilization and safety. The test will begin in a horizontal position and slowly move vertically to stimulate an upright position. The physician will closely monitor the heart rate and blood pressure as the table position changes, as POTS causes an increased heart rate and blood pressure when standing. Although fainting can occur, the individual is safely strapped to the tilt table, so there is no change of the individual falling and health care professionals are present the entire time. The tilt table test is a safe and effective way to diagnose POTS.
