Tilt Table Test
(Head-Up Tilt Table Test [HUT]; Passive Head-Up Tilt Test; Upright Tilt Test)
Definition
During a tilt table test, a person lies on a table. The table is then tilted from lying down to an upright position. The person’s heart rate and blood pressure are checked throughout the test.
Fainting may be due to decreased blood flow to the brain.

Reasons for Test
A tilt test is done to help diagnose the cause of unexplained fainting. The test tries to create the same conditions that may cause a person to faint.
Possible Complications
This test may lead to lightheadedness or fainting. If so, the care team will be there to help.
What to Expect
Prior to Test
You may be asked not to eat or drink for 2 to 4 hours before the test.
Description of Test
Electrode patches will be placed on the chest, legs, and arms. These patches connect to an ECG. An ECG is a device that checks the heart's electrical activity. Next, a blood pressure cuff will be placed on the arm to check blood pressure. An IV may also be placed in the arm. This is to take a blood sample or give medicine—if needed.
You will lie flat on a table. Safety straps will secure you. The table will be raised slowly until upright. You may stay in this position for 5 to 45 minutes. It depends on the reason for the test.
Your blood pressure and heart rate will be checked. While upright, you will need to stay as still as possible. You will be asked you how you feel throughout the test. If you faint or feel like you might faint, the table will be returned to a lying down position. If you do not faint, you may be given a medicine that can help with the diagnosis.
After Test
You can go home.
How Long Will It Take?
About 90 minutes
Will It Hurt?
During the test some people feel sick, lightheaded, or a fast heartbeat. The IV may cause some discomfort when first put in.
