Booking the appointment is often the hardest part. By the time most people reach a POTS specialist, they have already been to several other doctors, been told their tests look normal, and started to wonder whether they will be believed this time.
This guide walks through what actually happens at a first POTS appointment, what to bring, which tests may follow, and what questions are worth asking. Knowing the shape of the visit in advance makes it easier to use the time well.
Before your appointment
Keep a symptom record for two weeks
This is the single most useful thing you can do, and most people arrive without one. Your specialist needs to see the pattern, not just a description of a bad day.
For two weeks, note:
- What time of day symptoms are worst. Morning symptoms are common in POTS and that detail matters.
- What you were doing when symptoms started. Standing, showering, eating, heat, exercise, standing in a queue.
- How long episodes last and what helps them settle.
- Your heart rate lying down and again after standing for a few minutes, if you have a way to measure it at home. A simple fitness tracker or pulse oximeter is fine for this. Write both numbers and the date.
- Anything that has changed recently, including illness, surgery, pregnancy, injury, or a period of extended bed rest.
Bring the record with you, on paper or on your phone.
Gather your records
Bring or forward anything you already have:
- Previous ECGs, echocardiograms, monitor reports, and blood work
- Notes or letters from other doctors you have seen
- Any prior tilt table or autonomic test results
If records are held at another clinic, request them early. They often take longer to arrive than people expect.
Write down everything you take
Make a full list of prescriptions, over the counter products, vitamins, and supplements, with the amounts. Some products affect heart rate and blood pressure, and reviewing that list is part of the assessment. Do not stop anything before your visit unless the doctor who prescribed it tells you to.
Practical things for the day
- Ask the office when you book whether there is any preparation required, since some tests have instructions about eating, drinking, or timing.
- Wear or bring clothing that allows access to your arms and chest for monitoring.
- Plan your travel so you are not rushing in overheated and dehydrated, which can make your readings less representative of a normal day.
- Bring someone with you if you can. A second set of ears helps, and it is useful to have company if standing tests leave you lightheaded.
What happens during the visit
Your history comes first
Expect detailed questions. When did symptoms start, what triggers them, what makes them better, how they affect work, school, and daily life, and whether anything happened just before they began. Family history, other diagnoses, and your activity level all matter.
This part is not small talk. Expert consensus treats a complete history as a core part of assessing POTS, because the pattern of symptoms often points to the mechanism before any test does.
Orthostatic vital signs
Your heart rate and blood pressure are measured while you are lying down, then again at intervals after you stand. This is the measurement that so often never gets taken elsewhere, and it is central to the diagnosis.
The diagnostic threshold is a sustained heart rate increase of 30 beats per minute or more within 10 minutes of standing for adults, or 40 beats per minute or more for young people aged 12 to 19, alongside at least three months of orthostatic symptoms and without a significant drop in blood pressure.
If your readings are normal on the day, that does not close the question. POTS fluctuates, and symptoms are often stronger in the morning. Your specialist will decide whether a more controlled test is needed.
An ECG and an examination
A 12-lead ECG is standard at a first assessment, along with a physical examination. Together with your history and orthostatic readings, this is the baseline that determines what comes next.
Tests that may be scheduled
Not everyone needs every test. Your specialist orders based on your presentation, not as a routine panel. Depending on what the first visit shows, you may be scheduled for:
- Tilt table testing, which records your heart rate and blood pressure over a longer, controlled period than a bedside standing test allows
- Holter monitoring, a wearable monitor that captures your heart rhythm across a full day of normal activity
- 24-hour blood pressure monitoring
- An echocardiogram to assess heart structure and function
- Thyroid function tests and blood work to rule out other causes of a fast heart rate
- Autonomic nervous system testing or QSweat testing where a more detailed picture is needed
- A gastric emptying study or SIBO test if digestive symptoms are prominent
Ask what each test is for and when you will get the results. You are entitled to understand why something is being ordered.
Questions worth asking
Write these down before you go, because it is easy to forget them in the room.
- What did my standing heart rate and blood pressure show today?
- Do I meet the diagnostic criteria, and if not, what else could explain my symptoms?
- Which tests are you ordering, and what will each one tell us?
- What can I start doing now, before the results come back?
- Which of my current medications or supplements could be making symptoms worse?
- What should I do during a bad flare?
- When is my follow-up, and who do I contact if things get worse before then?
What happens after the appointment
A first visit rarely ends with a complete treatment plan, and that is normal rather than a sign that nothing is happening. The usual sequence is assessment, then testing, then a plan built around what the testing shows.
Once a diagnosis is established, care generally begins with non-drug measures: fluid and dietary salt targets set by your physician, compression garments, adjustments to how you sleep and move, and a structured exercise programme that starts with non-upright activity so it does not trigger your symptoms. Further treatment is considered from there, in consultation.
POTS management works over months, not in a single visit. Expect follow-up, expect adjustments, and expect the plan to change as your response becomes clear. You can read more about what treatment involves on our POTS treatment page, and about long-term outlook in our article on POTS prognosis.
If you have been dismissed before
Many people arrive at a POTS clinic carrying years of being told that it was anxiety, or that the tests were fine. In the largest patient survey conducted, people waited a median of two years between first seeing a physician and receiving a POTS diagnosis, and around 15% waited more than a decade.
That history is worth mentioning at your appointment rather than hiding. What you have already been tested for, what was ruled out, and what treatments have or have not helped are all useful clinical information. A specialist assessment starts from your symptoms and your measurements, not from what a previous clinic concluded.
Frequently asked questions
How long does a first POTS appointment take?
Longer than a standard consultation, because the history and orthostatic measurements take time. Our office will tell you what to expect when you book, so you can plan your day around it.
Do I need a referral?
Referral requirements depend on your insurance plan. Call our office on 214-504-9942 before your visit and our team will confirm what your plan needs.
What if my heart rate does not rise enough on the day?
That happens, because POTS fluctuates and readings vary by time of day. It does not end the assessment. Your specialist may arrange a tilt table test or extended monitoring to capture the pattern over a longer period.
Should I stop my medications before the appointment?
No. Do not stop or change anything on your own. Bring a full list instead, including supplements, and your specialist will review it with you.
Can I bring someone with me?
Yes, and it usually helps. A second person can take notes and drive you home if standing tests leave you lightheaded.
What if I have already been diagnosed elsewhere?
Bring the diagnosis and the testing behind it. A second opinion or a transfer of care starts from what already exists, and previous results often save repeating tests.
