Tilt Table Test

A tilt table test is used to determine the cause of unexplained fainting. During a tilt table test, you lie on a table and your heart rate and blood pressure are monitored as the tilt table moves from a horizontal to a vertical position. The test begins with you lying flat on a table and straps are put around the body to hold you in place. The table is tilted to raise your body to a head-up position - simulating a change in position from lying down to standing up. This test allows doctors to evaluate the body's cardiovascular response to the change in position. The doctor may recommend a tilt table test if he or she suspects that neurocardiogenic syncope is responsible for your fainting and needs a diagnosis to confirm it. Neurocardiogenic syncope happens when the part of the nervous system that controls blood flow changes the heart rate and lowers the blood pressure for a short time, causing less blood flow to your brain which in turn leads to fainting.
