Tilt Table Test

Heart Institute at Children’s Hospital of Pittsburgh of UPMC

The tilt table test is done to identify the cause of unexplained fainting spells known as syncope. Syncope may occur rarely or frequently, depending on the cause, and may be due to:

  • vasovagal syndrome—a sudden drop in blood pressure with or without a decrease in heart rate that is caused by a dysfunction of the nerves controlling the heart and blood vessels
  • arrhythmia or dysrhythmia—a heart rate that is too slow, too fast, or too irregular to maintain adequate blood flow to the body
  • valve disease—malfunction of one or more of the heart valves, which may cause an obstruction of the blood flow within the heart

When a child has episodes of syncope, the doctor will evaluate the child's medical history and perform a physical examination. If basic components of the exam or history do not reveal a potential cause for the syncope, and the child has no history of heart disease or a heart condition, then further diagnostic procedures, such as a tilt table test, may be scheduled.

The tilt table test attempts to identify the cause for the onset of syncope by making changes in posture from lying to standing. Your child will lie flat on a special bed or table while connected to EKG and blood pressure monitors. The bed or table is then elevated to an almost standing position to simulate the patient standing up from a lying position. The blood pressure and EKG are measured during the test to evaluate changes during the position changes. If the test causes an episode of syncope, then the probable cause of the syncope is vasovagal syndrome. The doctor can then prescribe specific treatment for the syncope once the cause is known.

If the test does not cause an episode of syncope, and/or the EKG and blood pressure recordings do not detect an abnormality, then additional tests or procedures may be scheduled to gather further diagnostic information.
