Tilt Table Test

A tilt table test evaluates how your body regulates blood pressure and heart rate when changing position from lying down to standing. It is most often used to investigate unexplained fainting (syncope), dizziness, or lightheadedness. The test helps doctors determine if these symptoms are related to problems with the autonomic nervous system, heart rhythm, or blood pressure regulation.

• Avoid eating or drinking for 2–4 hours before the test to reduce nausea risk.
• Continue or stop certain medications (such as blood pressure drugs) only as directed by your doctor.
• Wear comfortable clothing. Remove jewelry or accessories that may interfere with monitoring.
• Arrange for someone to accompany you, as you may feel weak or lightheaded afterward.

You will lie flat on a special table equipped with safety straps. Electrodes are placed on your chest to record heart rhythm, and a blood pressure cuff and oxygen sensor are attached. The table is then tilted upward to simulate standing, usually at a 60–80° angle. The test may last 20–45 minutes, during which you may experience symptoms such as dizziness or faintness. In some cases, medications are given to provoke a response.

• Most people tolerate the test well, though temporary fainting, nausea, or dizziness may occur.
• Rare complications include irregular heart rhythm or prolonged low blood pressure, which are quickly managed by the medical team.

Your doctor interprets how your heart rate and blood pressure respond during the test. Results help guide treatment, which may include hydration strategies, medications, or lifestyle adjustments. Further cardiac or neurologic testing may be ordered if needed.
