The head-up tilt table test is a way to find the cause of fainting spells. You lie on a bed and you’re tilted at different angles (from 30 to 60 degrees) while machines monitor your blood pressure, electrical impulses in your heart, and oxygen level.
It’s done in a special room called the EP (electrophysiology) lab.
How Should I Prepare for It?
If you’re scheduled for a head-up tilt table test, you should:
•Take all your medications, as prescribed.
•Not eat or drink anything after midnight the evening before your test. If you must take medications, drink only small sips of water to help you swallow your pills.
•Bring a list of all your current medications, including the dose.
•Wear comfortable clothes to the hospital. It is best not to wear any jewelry or bring valuables.
•Plan to have someone drive you home after your test.
•If you have diabetes, ask how to take your medications, eat, and drink before the procedure.
What Should I Expect?
It usually takes an hour or two to complete. That may vary, depending on how your blood pressure and heart rate change and what symptoms you have during it.
Before the test begins, a nurse will start an IV. This is so the doctors and nurses may give you medications and fluids during the procedure if necessary.
You’ll be awake during the test. They’ll ask you to lie quietly and keep your legs still.
