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.
A tilt table test is generally safe, and complications are rare. But, as with any medical procedure, it does carry a risk of complications.
