In short
- A tilt table test watches your heart rate and blood pressure as you are tilted nearly upright, to find a cause for fainting or feeling faint.
- A normal result does not rule out every cause of blackouts, and a positive result usually points to a common, often benign, fainting reflex.
- It is a monitoring test with no cuts or catheters; you may briefly faint or feel unwell during it, which is the point, under close supervision.
- Results are usually explained at a follow-up appointment rather than on the day.

What is a tilt table test?
A tilt table test is used to help find out why someone faints, feels faint, or has unexplained dizziness. Fainting usually happens without warning and with no one around to record what the heart and blood pressure were doing, so doctors often have little to go on. This test tries to bring on those symptoms safely, under close monitoring, so the cause can be seen.
You lie on a special padded table and are gently secured to it. The table then tilts you to a nearly upright position, around 60 to 70 degrees, while your heart rate and blood pressure are recorded continuously. Staff watch you closely throughout and can return the table to flat quickly if you feel unwell.
Sometimes a medicine spray under the tongue (GTN) is used to make a reaction more likely, or a gentle massage of the side of the neck is done. If your blood pressure or heart rate drops in a particular way and reproduces your symptoms, that points to a common, usually benign, cause of fainting.
It is an information test, not a treatment. It cannot, on its own, rule out every cause of blackouts, and a normal result does not always mean nothing is wrong — so it is interpreted alongside your history and other tests.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Tilt table test compared with other fainting tests
| Test | What it looks at | When it is used |
|---|---|---|
| Tilt table test | Blood pressure/heart rate when upright | Unexplained fainting or feeling faint |
| ECG / heart monitor | Heart rhythm over time | When an abnormal rhythm is suspected |
| Bloods / other tests | Anaemia, sugar, other causes | To rule out non-heart causes |
These tests often complement each other; the right combination depends on your symptoms. This is a guide, not advice — your doctor will decide what you need.
Preparing for your test
- Ask the team whether to take or hold any of your usual medicines, as some can affect the result.
- You will usually be asked to avoid caffeine for at least a few hours beforehand, as it can interfere with the test.
- You may be asked not to eat for a few hours before, though people with diabetes are often allowed a light meal — check what applies to you.
- Wear loose, comfortable clothing so electrodes and cuffs can be attached.
- Bring a current list of your medicines and any record you have kept of your fainting episodes.
- Arrange a lift if you think you may feel washed out afterwards, or if advised.
- Tell the team if you might be pregnant, or if you have had a recent illness.
What happens
You lie down on a padded table and are gently but securely fastened with straps so you cannot fall if you faint. A cuff on your finger and another on your arm measure your blood pressure, and sticky electrodes on your chest record your heart rhythm. Baseline readings are taken while you are lying flat.
The table then tilts you to a nearly upright position, around 60 to 70 degrees, and holds you there. You are not asked to stand on your own; the table supports you. Your blood pressure and heart rate are recorded continuously, often for up to about 45 minutes, while staff watch you closely.
If nothing happens, a GTN spray under the tongue, or a gentle neck massage, may be used to encourage a reaction. If you feel faint, sweaty, sick or actually faint, the team lowers the table flat straight away and you usually recover quickly. The whole appointment commonly takes up to an hour.
Is this test right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- When the cause of blackouts is more likely a heart-rhythm problem, where a heart monitor or other cardiac test is the right first step.
- When blackouts are clearly explained by another cause (for example a known rhythm disorder, low blood sugar or a medicine), so the test would add little.
- When standing nearly upright for a prolonged period is unsafe for the person.
- When red-flag features (such as blackouts during exertion or a strong family history of sudden death) need urgent cardiac assessment first.
Delay or rearrange if…
- A recent illness or being acutely unwell on the day.
- Medicines that affect the result have not been adjusted as advised.
- Caffeine or food rules for the test have not been followed.
- Possible pregnancy, until discussed, if GTN provocation is planned.
Alternatives to discuss
- An ECG or longer-term heart-rhythm monitor where a rhythm cause is suspected.
- An active stand test (lying-to-standing blood pressure measurements) for some patients.
- Blood tests to look for anaemia, low sugar or other causes.
- A review of medicines and history, sometimes without any tilt test at all.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Benefits
- Can reproduce your symptoms under monitoring, helping pin down the cause of fainting
- Can identify a common, usually benign, fainting reflex so you can be reassured and advised
- Can help diagnose conditions such as PoTS or a sensitive neck reflex
- Helps separate simple fainting from rhythm problems that need different treatment
- May reduce the need for more invasive tests if it gives a clear answer
Risks & complications
- Feeling faint, sweaty, sick or actually fainting during the test — this is expected and closely supervised
- Feeling washed out, tired or a bit shaky for a short time afterwards
- Headache from the GTN spray, if it is used
- A longer-lasting feeling of being unwell after a strong reaction
- A clear reaction that does not match your usual symptoms, leaving the picture uncertain
- Needing the test repeated or other tests if the result is inconclusive
- A prolonged faint with a very slow heartbeat or pause, which the team manages by lying you flat
- A more serious heart-rhythm disturbance, very rarely, in a closely monitored setting
The main 'risk' is that the test deliberately tries to make you feel faint or faint, which can be unpleasant but is done under close supervision with staff ready to lay you flat. The bigger limitation is interpretation: a normal result does not rule out every cause of blackouts, and a positive result has to match your real-life symptoms to be meaningful. Ask what the result will change and what happens if it is normal or unclear.
Published figures to discuss
The tilt table test is low-risk; the main 'event' is a faint, which is intentional and supervised. Its accuracy is limited: it can miss the cause (a normal result does not exclude fainting) and can sometimes produce a reaction that does not match a person's real symptoms. We describe these limitations qualitatively rather than quoting precise accuracy figures, which vary by protocol.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Fainting or near-fainting during the test | Expected possibility and sometimes the intended diagnostic event | The table straps and monitoring make this controlled; staff can return the table flat promptly. | Guide sourcesClinical context |
| Low blood pressure, weakness, dizziness or unsteadiness afterwards | Recognised; usually temporary | These symptoms generally settle after lying flat and resting, but patients may feel washed out for a few hours. | Tilt Table Test: State of the Art (PMC)ncbi.nlm.nih.govSource-linked context |
| Serious complication | Rare | The test is generally safe, but patients with concerning cardiac features need appropriate cardiac assessment and monitoring. | Tilt Table Test: State of the Art (PMC)ncbi.nlm.nih.govSource-linked context |
| False-negative or non-representative result | Recognised | A normal test does not rule out all causes of blackouts, and a positive reaction is most useful when it reproduces the person's usual symptoms. | Guide sourcesClinical context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
There is no physical recovery from the test itself. Most people feel fine soon after lying flat, though some feel washed out or tired for a little while, especially if they had a strong reaction or the GTN spray was used.
- Feeling faint or fainting during the test, then recovering quickly once flat
- Feeling washed out, tired or shaky for a short time afterwards
- A short-lived headache if the GTN spray was used
- Not getting the result on the day — it is usually discussed at a follow-up
Aftercare
- Rest until you feel steady before leaving, and get up slowly.
- Eat and drink normally afterwards, and have a snack if you feel shaky.
- Avoid driving or anything risky until you feel completely back to normal, especially if you fainted.
- Restart any medicines you were told to hold, as directed.
- Make a note of any symptoms during the test to discuss at your follow-up.
- Wait for the referring doctor to contact you with the result, and chase it if you do not hear.
- Keep any advice you are given about managing fainting (such as fluids, salt or simple manoeuvres).
- Clear instructions on which medicines to hold or take beforehand
- Caffeine avoided for the period advised
- Loose, comfortable clothing for electrodes and cuffs
- A note of your fainting episodes to bring with you
- A lift arranged if you may feel washed out afterwards
- A follow-up appointment booked to discuss the result
- Any fainting self-management advice noted down
⚠ Get urgent help if…
- Chest pain, severe breathlessness or a fast pounding heartbeat after the test — seek urgent advice; call 999 if severe
- Fainting again at home, especially without warning or with injury
- A severe or persistent headache after the GTN spray
- Feeling very unwell, confused or unable to recover your usual self
- Signs of a stroke: face drooping, arm weakness or slurred speech — call 999
- Any blackout while driving — stop driving and seek advice before driving again
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A useful result is one that reproduces your usual symptoms while the monitors show what your heart rate and blood pressure are doing. A drop in blood pressure or heart rate that brings on your symptoms points to a common fainting reflex (vasovagal syncope); a sharp rise in heart rate on tilting can suggest PoTS.
A normal test does not prove there is nothing wrong — fainting is intermittent, and the test may simply not trigger it on the day. Equally, a reaction that does not match your real symptoms can be misleading. That is why the result is always interpreted alongside your history and other tests, and why it is usually explained at a follow-up rather than handed to you on the day.
The result reflects how your body responded on the day of the test. Fainting tendencies can change over time, and a normal test does not mean future blackouts are impossible. If your symptoms change or worsen, the test may need repeating or other investigations may be needed.
Related tests, treatments or support
A tilt table test is often done as part of a wider assessment for blackouts that may include an ECG, a longer-term heart-rhythm monitor, blood tests and a review of your medicines. Carotid sinus massage is sometimes done at the same visit. The aim is to build a complete picture rather than rely on one test.
Follow-up & long-term care
The findings are sent to the doctor who referred you, who will normally contact you to discuss them and explain any diagnosis, advice or further tests. If the result is inconclusive, you may be offered repeat or additional testing, or longer-term heart-rhythm monitoring.
Repeat, follow-on and what comes next
- An inconclusive or normal test sometimes needs repeating, or other tests such as longer-term heart-rhythm monitoring.
- A positive result still has to match your real symptoms to be acted on.
- Fainting tendencies can change over time, so testing may be revisited if symptoms change.
- The diagnosis may be refined as more information from monitors or further tests comes in.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A clear explanation of the result, interpreted alongside your history and other tests.
- Practical advice on managing fainting if a benign cause is found (fluids, salt, simple manoeuvres).
- A plan for further tests if the result is normal or unclear.
- Clear guidance on driving while blackouts are being investigated.
- A named contact and a route to discuss results and next steps.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- The clinic or facility fee for the monitored test
- The cardiologist's or physiologist's time and reporting
- Whether GTN provocation or carotid sinus massage is included
- Any tests done alongside, such as an ECG or longer-term heart monitor
- A follow-up appointment to discuss the result
- Whether repeat or further testing is needed if the result is inconclusive
- The facility fee and the clinician's reporting fee
- Whether GTN provocation or carotid sinus massage is included
- Whether any tests done alongside are included or charged separately
- A follow-up appointment to explain the result
- The cancellation policy
- What happens, and what it costs, if the result is inconclusive and repeat testing is needed
On the NHS? A tilt table test is available on the NHS when clinically indicated; private testing is usually chosen for speed or choice of clinic, not because the test is otherwise unavailable.
You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.
Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Not being told the test deliberately tries to make you faint, and what that feels like.
- Treating a normal result as proof that nothing is wrong.
- Acting on a positive result that does not actually match your usual symptoms.
- Not explaining when and how you will get the result.
- Not discussing driving rules while blackouts are being investigated.
Marketing red flags
- Suggesting the test can 'rule out' all causes of blackouts.
- Offering it as a standalone answer without considering rhythm or other tests.
- Implying a same-day definitive diagnosis is guaranteed.
- Not mentioning the limitations or the chance of an inconclusive result.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- What will this test change about my diagnosis or treatment?
- What happens if the result is normal, positive or inconclusive?
- Will you use the GTN spray or neck massage, and what should I expect?
- Do I need any other tests, such as a heart-rhythm monitor, alongside this?
- What should I do about driving while my blackouts are being investigated?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my test, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this test not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
