A Patient's Guide to the POTS Tilt Table Test
Are you curious about what happens during a tilt table test for POTS? Whether you’re researching how Postural Orthostatic Tachycardia Syndrome (POTS) is diagnosed or preparing for an upcoming appointment, understanding this key diagnostic tool can help ease your mind and boost your confidence.
Despite its technical name, the tilt table test is just a simple, straightforward way to measure how your body responds to position changes—one of the defining challenges of POTS.
Essential Takeaways:
- Why Use the Tilt Table Test? Doctors and POTS specialists rely on the tilt table test to assess how your body manages blood pressure and heart rate changes when upright. It’s one of the best tools available for diagnosing POTS and developing a personalized treatment plan tailored to your needs.
- Preparation Can Make the Test Easier: Simple steps like avoiding caffeine, fasting if advised, and wearing comfortable clothing can help you feel more at ease during the tilt table test, ensuring clearer results and a smoother experience.
Let’s go through everything you need to know, from preparing for a tilt table test to what your results mean for you. This guide will help you understand every part of the test, so you can walk into it feeling informed and prepared.

What is the Tilt Table Test?
The tilt table test measures how your body responds to position changes, making it a key diagnostic tool for conditions like POTS. During the test, you lie flat on a specialized table that tilts you from a horizontal to an upright position while healthcare professionals monitor your heart rate and blood pressure.¹
Why It’s Used
This POTS diagnosis test helps doctors diagnose several conditions, particularly POTS, orthostatic hypertension, and irregular heartbeats, called arrhythmias.
For those with POTS, the simple act of going from lying down to standing can trigger significant heart rate increases and symptoms like dizziness. The tilt table test captures these responses in a controlled, safe environment.¹
The tilt table test is just one tool for diagnosing POTS. To learn more about the entire process, check out our Guide to Getting Diagnosed with POTS.
What to Expect During the Test
Understanding what happens during the tilt table test for POTS can ease your nerves and help you feel more prepared. Here’s a step-by-step look.
Initial Setup
Once you arrive at the clinic, a healthcare professional will explain the procedure, answer any questions, and attach monitoring devices, including chest electrodes and a blood pressure cuff.
The Testing Process
The table gradually tilts to a near-upright angle, usually between 60-80 degrees, simulating a standing position. You’ll remain in this position for 20-45 minutes while providers monitor your vital signs.
Observation Period
During this time, you may experience typical POTS symptoms like dizziness, increased heart rate, or lightheadedness. These reactions help your healthcare team understand how your body responds to position changes.
Test Duration
The entire process usually takes 30-90 minutes, depending on your symptoms and responses. In some cases, medication may be administered to help trigger certain nervous system responses.
Completing the Test
The test ends with a brief rest period as you lie flat, allowing providers to take final measurements and ensure you’re stable before leaving.
While the tilt table test is generally safe, some patients may experience temporary symptoms like low blood pressure, weakness, or dizziness during the test. Your healthcare team will monitor you closely throughout the entire process.¹ ²
Preparing for the Tilt Table Test
Being well-prepared for the test can make it a much more positive experience. Here are some tips on preparing for a tilt table test:
- Follow Dietary Guidelines: Your doctor may recommend avoiding certain foods or drinks for at least 24 hours before the test, as they can affect heart rate, blood pressure, and overall test results. This may include caffeine, sugary foods and drinks, alcohol, high-sodium foods, and large or heavy meals.
- Fasting: Some doctors may recommend fasting for a few hours before the test.
- Wear Comfortable Clothing: Loose, comfortable clothes can help you feel more at ease and make position changes easier.
- Bring a Support Person: Having someone drive you home is helpful, as you may feel weak and dizzy after the test.¹ Learn how to build a support network with our guide to POTS and Relationships.
Remember to check with your healthcare provider for any additional guidelines based on your specific needs.
Understanding the Results of the Tilt Table Test
Your tilt table test results provide valuable insights into your autonomic nervous system function, particularly how your body manages blood pressure and heart rate when upright. Here’s how doctors interpret the results:
- Heart Rate: A notable increase in heart rate (often 30+ beats per minute) upon tilting is a primary indicator you have POTS.³
- Blood Pressure: Fluctuations in blood pressure, such as a sudden drop or an abnormal increase, can further signal issues in the body’s regulation system.
- Positive Result: A significant drop in blood pressure or changes in heart rate, combined with symptoms like dizziness or fainting, suggests autonomic dysfunction, which may point to POTS or other related conditions like bradycardia (slow heartbeat), tachycardia (fast heartbeat), or hypotension (low blood pressure).
- Negative Result: If your heart rate only increases slightly, and your blood pressure remains stable without any symptoms of fainting, the results may indicate that another cause is responsible for your symptoms. Your healthcare provider may suggest further testing if necessary.¹ ²
These findings can guide the next steps in diagnosis, helping your healthcare provider recommend targeted treatments or lifestyle modifications. Learn more with our guide: How to Create a POTS Management Plan.
Post-Test Care: What to Do After
After the test, some patients feel lightheaded, tired, or slightly nauseated. Here’s how you can care for yourself post-test:
- Hydrate: Drinking water or an electrolyte drink can help restore hydration and aid in recovery.
- Rest: It’s natural to feel fatigued, so rest when you get home.
- Watch for Lingering Symptoms: Some lightheadedness may linger for a few hours, but if you experience prolonged or severe symptoms, contact your doctor.
Following these recovery steps will help you transition comfortably back to your regular routine while giving your body the care it needs after the tilt table test.¹
Getting Ready for Your POTS Journey
While the tilt table test for POTS may seem daunting at first, it’s an invaluable diagnostic tool that helps your healthcare team understand and manage your condition. Remember, being informed and prepared can make the entire process much smoother.
Don’t hesitate to discuss any concerns with your doctor before the test—they’re there to help you through each step of your journey.
