A tilt table test is a test for investigating the causes of faints. Simple faints, also called vasovagal syncope or neurocardiogenic syncope, occur when something triggers an exaggerated response from the body’s control system.
This results in an excessively low blood pressure and on rare occasions, excessively slow heart rate, which can make people feel faint, or even pass out. After fainting, the body is able to correct itself without treatment by assuming the lying down position.
There are three components to this test, postural blood pressure test, carotid sinus massage test and the tilt table test itself.
Tilt table testing is designed to try to trigger a faint so that we can confirm the diagnosis and observe what actually happens.
