Tilt-table Test
What is the tilt-table test?
The tilt-table test is aptly described by its name. It involves placing a patient on a table with a foot-support. The table is then tilted upward. The tilt-table may start off in a horizontal position and be tilted by degrees to a vertical position.
What is done during the tilt-table test?
The patient's blood pressure and pulse and symptoms are recorded with the patient in each position.
Why is the tilt-table test done?
The tilt-table test is designed to detect one of the most common causes of fainting, postural hypotension (orthostatic hypotension).
What is postural hypotension (orthostatic hypotension)?
Postural hypotension is a common cause of an episode of temporary loss of consciousness. Postural hypotension results from changing body position from a prone, supine or sitting position to a more vertical position. Poor tone of the nerves to blood vessels in the legs can cause a disproportionate distribution of blood to the legs, instead of to the brain, so a person feels lightheaded and may even faint.
When is the tilt-table test done?
Tilt-table testing may be done when heart disease is not suspected of being responsible for an attack of fainting (syncope) or near-syncope.
What happens after the tilt-table test?
Depending on the presence or absence of signs and symptoms during the tilt-table test, persons with certain forms of temporary loss of consciousness may be admitted to the hospital for observation and further testing. The tilt-table test is also performed on stabilized patients who are in the hospital for evaluation of the cause of temporary loss of consciousness.
Does the tilt-table test hurt?
No. It doesn't hurt. However, patients may experience symptoms such as feeling lightheaded, nauseated, sweating, or weakness. Any symptoms recorded during the test can help the doctor to diagnose the cause of an episode of temporary loss of consciousnes.
The tilt-table test sounds simple. Is it?
Yes, it is a simple, inexpensive, and informative test.
