What is a Tilt Table Test?

A Tilt Table Test (TTT) may be ordered for a patient who has unexplained fainting, or syncope, in order to determine the cause of this fainting. It is done by placing a patient on a table, which has a foot-board. A BP cuff and electrodes are connected to a patient, along with an IV, so it is helpful if a patient wears loose clothing. There is no sedation given for this test. The table is tilted up to a standing position (head up), and the patient’s blood pressure and heart rate are monitored for about 45 minutes. The doctor will be able to give some answers to address what may have been causing this fainting or dizziness. The test may show neurocardiogenic syncope or orthostatic hypotension, among other possibilities.

Preparation for this test involves not eating or drinking for about 2-3 hours before coming in. If the TTT is in the morning, a patient may have a glass of something to drink when he first gets up, followed by no more food or drink before the procedure.
