The Head-Up Tilt Test, also known as the tilt table test, is a medical procedure used to evaluate and diagnose the cause of fainting spells or episodes of unexplained loss of consciousness. It is primarily conducted to assess orthostatic hypotension, a condition characterized by a sudden drop in blood pressure upon standing up.
During the tilt table test, the patient is secured to a special table that can be tilted to different angles, ranging from a horizontal position to an upright position of about 60 to 80 degrees. The table is equipped with safety straps to prevent the patient from falling. The patient's heart rate, blood pressure, and other vital signs are continuously monitored throughout the procedure

Why is a Head-Up Tilt Test done?
A Head-Up Tilt Test is performed to evaluate the cause of unexplained fainting episodes or lightheadedness. It helps determine if a drop in blood pressure or heart rate is responsible for the symptoms. The test can aid in diagnosing conditions such as vasovagal syncope, postural orthostatic tachycardia syndrome (POTS), and certain autonomic nervous system disorders.
How long does a Head-Up Tilt Test take?
The duration of a Head-Up Tilt Test can vary, but it typically lasts between 30 minutes to an hour. The exact duration depends on the specific protocol followed by the medical team and how quickly symptoms are provoked.
What can I expect during the Head-Up Tilt Test?
During the test, you may experience symptoms such as lightheadedness, dizziness, palpitations, or even fainting. These symptoms are often induced intentionally to help diagnose the underlying cause. The medical team will closely monitor your vital signs and symptoms throughout the procedure to ensure your safety.
Is the Head-Up Tilt Test a safe procedure?
The Head-Up Tilt Test is generally considered safe. However, like any medical procedure, there are some risks and potential complications, although they are rare. These can include a drop in blood pressure leading to fainting, irregular heart rhythms, and extremely rarely, more serious complications such as a heart attack or stroke.
