A Tilt table test is done to determine the cause of unexplained fainting or loss of consciousness. It is a non-invasive test. The test involves moving from a lying to a standing position and monitoring your vital signs and symptoms. The test records your blood pressure, heart rate, and heart rhythm when the table is tilted to different angles. The table is kept head up.
The test also helps to diagnose orthostatic hypotension. Orthostatic hypotension is when the blood pressure drops excessively when you stand up. This occurs due to a sudden dilation of the blood vessels in your legs that slows down the heart rate. This reflex may be caused due to anxiety, fatigue, or physical stress. When you have one of these conditions, your body does not adjust when you stand normally and you experience loss of consciousness or changes in your physical conditions when you are moved from a lying position to an upright position during a tilt test. The test also helps in distinguishing epilepsy from fainting.
