A tilt table test is used to evaluate the cause of unexplained fainting (syncope).
Your doctor may recommend a tilt table test if you've had repeated, unexplained episodes of fainting. A tilt table test may also be appropriate to investigate the cause of fainting if you've fainted only once, but another episode would put you at high risk of injury due to your work environment, medical history, age or other factors.
For a tilt table test, you begin by lying flat on a table. Straps are put around your body to hold you in place. After about 15 minutes of lying flat, the table is quickly tilted to raise your body to a head-up position — simulating a change in position from lying down to standing up.
The table will then remain upright for up to 45 minutes, while your heart rate and blood pressure are monitored. This allows doctors to evaluate your body's cardiovascular response to the change in position.
