A tilt table test is used to check people who have fainted or who often feel lightheaded. The results help your doctor know the cause of your fainting or feeling lightheaded.
The test uses a special table that slowly tilts you to an upright position. It checks how your body responds when you change positions.
Why It Is Done
This test is done to find out why you might be having certain symptoms, such as fainting or feeling lightheaded. Your doctor can see if your symptoms are caused by problems with your heart rate or blood pressure.
How To Prepare
- You may be asked to not eat or drink for a few hours before the test.
- You may need to have someone drive you home after the test.
- Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your test. Your doctor will tell you if you should stop taking any of them before the test and how soon to do it.
How It Is Done
- The test is usually done in a hospital or a cardiologist's office.
- You will have small patches or pads attached to your skin. These are sensors that monitor your heart. You will also have a blood pressure cuff on your arm. And you may have an IV.
- During the test, you will lie flat on a table that can tilt you up to almost a standing position. You will be strapped securely to the table.
- Your heart rate and blood pressure are checked regularly as the table is tilted up.
- You will be asked if you feel any symptoms like nausea, sweating, dizziness, or an abnormal heartbeat. If you don't have any symptoms, you may be given medicine to speed up your heart rate. Then you will be checked for symptoms again.
- If you faint during the test, the table will be returned to a flat position. You will be checked closely and taken care of right away by your medical team. Most people wake up right away.
- Your heart rate and blood pressure will be checked before you go home.
How long the test takes
The test will take about an hour. It may take longer if you get medicine to speed up your heart during the test.
The test result is normal if your blood pressure stays stable during the test and you do not feel lightheaded or faint. The test result is not normal if your blood pressure drops and you feel lightheaded or faint. These symptoms might happen because of a slow heart rate.
