Tilt Table Test: What Happens, How to Prepare and What Results Mean

What is a tilt table test?

A tilt table test shows how your heart rate and blood pressure react when your body position changes. [2] You lie on a padded table with straps and a footrest. The table then tilts you from flat to nearly upright. This is like standing up, but you do not use your leg muscles to hold yourself up. [3]

It is also called a head-up tilt test. [3] [4] Throughout the test, sticky ECG patches on your chest record your heart rate and rhythm. Cuffs on your arm and finger measure your blood pressure, and the finger cuff can measure it with every heartbeat. [3] [5]

What does a tilt table test diagnose?

Doctors may suggest a tilt table test if you faint and the cause is not known, have repeated falls, or often feel faint or lightheaded. [2] It can help find or rule out: [2] [3]

• Postural tachycardia syndrome (POTS): your heart beats faster than it should when you stand up [2] [3]
• Vasovagal syncope, a type of reflex syncope: a sudden drop in blood pressure, sometimes with a slower heartbeat, makes you faint. Triggers include stress, tiredness and medical procedures [2] [3]
• Orthostatic hypotension: your blood pressure drops more than it should when you stand up [2] [3]
• Psychogenic pseudosyncope: something that looks like fainting but happens without a drop in blood pressure [2]

A tilt table test is not used to find fainting caused by heart rhythm problems or other heart conditions. Doctors usually check for those first. [2] [3]

In the UK, NICE guidance for doctors says a tilt test should not be the first test when a heart rhythm problem is suspected. It also says not to offer one if your first assessment already shows vasovagal syncope. For unexplained fainting, NICE says to offer an ambulatory ECG (a heart monitor you wear) before any tilt test. [12]

For POTS, the NHS says a GP may first check your heart rate and blood pressure before and after you stand up. If you are referred, a specialist may then do a tilt table test. [1] Our guide to how POTS is diagnosed covers the whole process.

What happens during a tilt table test?

Each hospital has its own way of doing the test, so the details vary. [8] This is the usual order:

GTN widens your blood vessels and lowers your blood pressure, which can help bring on your symptoms. [4] Cleveland Clinic says medicines are used less often than they used to be. [3]

Some hospitals do the test in a quiet, dim room, so family and friends may not be allowed in. [4] A member of staff stays with you the whole time, and you can ask to stop at any point. [5] One NHS hospital notes that once the test is stopped, it cannot be restarted. [4]

How long does a tilt table test take?

Allow up to 2 hours. NHS hospitals give different times: University Hospitals Sussex says the test can take up to 1 hour, and Royal Papworth Hospital says the appointment can last 1 to 2 hours. [4] [5]

The time on the tilted table is 5 to 45 minutes, depending on why you are having the test. If a medicine is used, you stay upright for up to 20 minutes more. [2] [7] The European Society of Cardiology’s fainting (syncope) guidelines suggest at least 20 minutes and no more than 45 minutes upright before any medicine. [7] When doctors are looking for POTS, at least 10 minutes of tilt is used. [9]

Afterwards, you may feel tired or have an upset stomach. [3] It can help to keep the rest of the day free.

Does a tilt table test hurt?

No. The test does not hurt, but you may feel lightheaded or faint during or after it. [4] The finger cuff feels like a constant squeeze on your finger, but it is not painful. [5] If your hospital gives a medicine through a vein, you will have a needle in your arm. [2]

Many people feel anxious about fainting during the test. Symptoms brought on by the test usually ease quickly once you are lying flat again. [4]

Is a tilt table test safe?

Mayo Clinic says the test is generally safe and complications are rare. Possible effects include fainting, low blood pressure, feeling dizzy or lightheaded and, rarely, an irregular heartbeat such as atrial fibrillation. These often go away when the table is flat again. [2]

The European syncope guidelines say there have been no reported deaths during the test. Minor side effects are common: GTN can cause a headache, and isoproterenol (the medicine given through a vein) can cause palpitations. Atrial fibrillation brought on by the test usually stops on its own. [7]

Some people faint during the test. You are strapped in and watched closely, so you do not fall. If you faint, the table goes flat straight away, and most people come round almost right away. [2] Some people pee when they faint. [3]

The test may not be safe if you are pregnant or have blocked arteries supplying your heart or brain, so your medical history is checked first. [3]

How do you prepare for a tilt table test?

Follow the letter from your own hospital, because instructions differ. Here are three examples:

You may also be asked to:

• tell the team about every medicine and supplement you take. Some change your heart rate or blood pressure, so you may be asked to stop some for a short time. Do not stop any medicine unless your care team tells you to [2]
• check with your GP if you take erectile dysfunction tablets such as sildenafil or tadalafil. One NHS hospital asks you to stop these for 24 hours before the test [2] [4]
• not smoke or use nicotine on the day [2]
• tell the team about any health conditions, such as a heart condition or a past stroke, and whether you are pregnant [2] [4]
• wear loose clothes so the ECG patches can go on your chest easily, and bring a list of your medicines [4] [5]
• empty your bladder before the test starts [8]

If the test is looking for POTS, medicines that raise your heart rate, such as stimulants, can make the result hard to read. A review of tilt testing says these should be paused when POTS is being considered, and that POTS should not be diagnosed when a medicine explains the fast heart rate. [8] Ask your specialist which of your medicines to stop, and when.

Time of day matters too. Heart rate rises more on standing in the morning than later in the day, so morning tests are likely to pick up POTS more easily. [8] [9]

What do tilt table test results mean?

A result is positive when your body reacts abnormally, usually with symptoms such as dizziness or fainting and a clear change on the monitors. It is negative when your heart rate goes up only a little, your blood pressure does not drop much and you do not faint. [2] [3]

Your doctor reads the monitor results together with your symptoms and medical history to reach a diagnosis. [3] They may repeat the test or suggest more tests. [2] [3]

Can a tilt table test be wrong?

Sometimes. A positive result shows that your body tends to react this way. It does not prove that this is what causes your symptoms day to day. [6] [11] In tests that used a medicine, about 11 to 14 in 100 people who had never fainted still had a positive result. [6]

Results can also change from one test to the next: when people with a positive result are tested again, the second result is not always positive. A normal result does not always rule things out either. For example, a tilt table test can miss the brief drop in blood pressure some people get in the first seconds after standing up. [8]

Do you need a tilt table test to diagnose POTS?

Not always. Expert reviews say POTS can usually be diagnosed with a 10-minute active stand test, where your heart rate and blood pressure are measured lying down and then standing. A tilt table test can be used, but it is not necessary. [9] [10]

Your heart rate tends to rise slightly more on a tilt table than when you stand, so a tilt test can pick up POTS a little more easily. Specialist centres often use it because it can be combined with more detailed monitoring. [9] A tilt table test can be most useful if:

• your stand test was normal, but your doctor still strongly suspects POTS [11]
• your doctor suspects you also have vasovagal syncope, or nerve damage that affects your heart rate and blood pressure (autonomic neuropathy) [10]
• you cannot stand for 10 minutes [10]

Your heart rate rise can change from day to day. If a doctor still suspects POTS after a normal test, the CMAJ review says it is sensible to check again on another day, ideally in the morning. [9]

Some people record their own lying and standing heart rate at home before an appointment. Juno’s free standing test timer helps you log those readings and print them for your doctor. It is not a tilt table test and cannot diagnose POTS. Only do it if you can stand safely, with someone nearby. If standing up makes you dizzy, our guide to feeling dizzy when standing up covers other common causes.

What should you write down after the test?

The report usually goes to the doctor who referred you, who then talks you through the results. [4] [5] It helps to note a few things while they are fresh:

• which symptoms you had on the table, and roughly when they started
• whether they felt like your usual symptoms
• whether you fainted, and how long it took to feel normal again
• how you felt that evening and the next day
• which medicines you paused, and for how long

Take these notes, and any dated heart rate readings from home, to your results appointment. Our free symptom tracker worksheet and appointment one-pager help you put it all on one page. If you already have POTS, our guide to POTS flare-ups covers bad days.

Juno can also help. You log symptoms by voice or text, and Juno turns them into a dated summary for your appointment. Juno does not diagnose POTS. See the POTS symptom tracker page.

When should you get urgent help?

It is rare for severe symptoms to carry on after a tilt table test, but if they do, you may need emergency care. [3]
