The Tilt Table Test is used to determine a cause of syncope (fainting or loss of consciousness). There can be different reasons people experience syncope. For some people it is related to an abnormal nervous system reflex causing the heart to slow and the blood vessels to dilate (open up) lowering the blood pressure. When this happens there is a reduced amount of blood to the brain causing one to faint. This type of syncope is called vasovagal, neurocardiogenic or abnormal vasoregulatory syncope and is considered benign (not dangerous or life-threatening), except for the injuries that can happen when one faints unexpectedly.
The Tilt Table Test is performed to reproduce (bring on) symptoms of syncope while the person is being closely monitored. The patient is positioned on a table that is tilted to a preset angle. Blood pressure and heart rate are constantly monitored.
