What is the purpose of a tilt table test?

• A. To monitor blood glucose levels
• B. To evaluate causes of unexplained syncope or lightheadedness
• C. To assess heart rhythm abnormalities
• D. To measure lung capacity

Answer: (B)

The tilt table test is specifically designed to evaluate causes of unexplained syncope (fainting) or lightheadedness. During the test, a patient is strapped to a table that can be tilted to various angles while monitoring their heart rate and blood pressure. This process helps determine how changes in position affect blood flow and cardiovascular responses, which can identify problems such as orthostatic hypotension or autonomic nervous system dysfunction.

The test is particularly useful for patients who suffer from recurrent episodes of syncope without a clear diagnosis, providing valuable insights that help guide further treatment and management. By assessing how the body responds to tilting from horizontal to an upright position, medical professionals can gather critical information about the mechanisms behind the patient's symptoms.
