A tilt table test is used to check people who have fainted or who often feel light-headed. The results help your doctor know the cause of your fainting or feeling light-headed.
The test uses a special table that slowly tilts you to an upright position. It checks how your body responds when you change positions.
This test checks what causes your symptoms by monitoring them while changing your position. Your doctor can see if you faint or feel light-headed because of problems with your heart rate or blood pressure.
When people move from a lying position to an upright one, their blood pressure normally drops. But the body adjusts to this. Your nervous system senses changes in body position and controls your heart rate and blood pressure.
If the nervous system doesn't work properly, you might feel light-headed or faint. This can happen if your blood pressure stays too low. Your heart rate also may slow down or speed up. You feel light-headed because your brain is not getting a normal amount of blood for a short time. This problem is called syncope (say "SING-kuh-pee"). Syncope might happen during the test when you change to an upright position.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
