Tilt-Table Test

Medical Author: Melissa Conrad Stöppler, MD
Medical Editor: William C. Shiel Jr., MD, FACP, FACR

What is the tilt-table test?

The tilt-table test is a simple, inexpensive, and informative test that can help identify the causes of fainting. As its name implies, the tilt table test involves placing a patient on a table with a foot-support, then tilting the table upward. The tilt-table may start off in a horizontal position and be tilted by degrees to a completely vertical position. The patient's blood pressure, pulse, and symptoms are monitored throughout the test.

Orthostatic hypotension is the term used to describe the fall in blood pressure when a person stands (orthostatic= upright posture of the body; hypo= less + tension=pressure).

Adequate blood supply to the body's organs depends upon three factors:

  1. a heart strong enough to pump,
  2. arteries and veins that are able to constrict or squeeze, and
