Tilt Table Studies/Tilt Table Testing (TTT’s): A tilt table test may be advised for some people who have had recurrent fainting episodes (syncope). This test shows how your heart rate and blood pressure respond to a change in position from lying down to standing up. In this test, an intravenous line is usually started in case medications need to be administered during the test. A catheter may also be placed in the artery to monitor blood pressure from inside the artery.
