Dysautonomia and POTS, when the heart tests come back normal

Your heart races when you stand up, you feel shaky inside, and the tilt table or the heart tests came back normal. Then the label became anxiety.

in their words

What people say about dysautonomia and POTS

"I know that something isn't right, but my tilt table results came back normal."

"I'm starting to feel like maybe I'm crazy because they can't find anything wrong with me"

"I Feel Like I'm Shaking Inside, but No One Can See It"

Why it is often missed. Heart and blood tests can come back normal, and then the label becomes anxiety. The part of the nervous system that regulates heart rate and blood flow is seldom what was measured.

Why the upper neck may be involved. The autonomic nervous system runs heart rate, blood pressure, digestion and temperature without you thinking about it, and the brainstem, which the top bone of the neck surrounds, is one of its main control centers. That is why we look at the upper neck and measure how the autonomic system is regulating, starting with heart rate variability.

what the research looked at

What the research has and hasn't looked at

There is little published upper cervical research on dysautonomia or POTS itself, and we haven't found a verified study on either. The closest research measured heart rate variability and blood pressure, two things the autonomic nervous system controls, and even there the results are mixed.

The closest research:

The closest studies, by design and year

6 studies, published 2001 to 2025. Strongest design: controlled trial. 1 in the NUCCA lineage, ringed.

how we measure

The Lazar Method™ measures first

Everyone else told you what might work. We measure before anything is decided. Heart rate variability shows how much reserve your nervous system has and whether it is stuck in fight or flight, and thermal scans read the part of your nervous system that runs the organs.

Before any correction we measure how your nervous system is regulating your body: heart rate variability, thermal and muscle tone scans, PostureIQ™, and digital X-ray of the upper neck. Dr. Jonathan Lazar, D.C., or someone personally trained by him, will go over your scans and images with you. QSM3, the method used at our office, is a progression of NUCCA, and the correction is gentle and specific: no cracking, no twisting.

If we can help, we'll tell you. If we can't, we'll help you find someone who can.

Sample heart rate variability chart: autonomic activity against balance
A sample heart rate variability chart: how the nervous system balances fight or flight with rest and digest.
Heart rate variability, in plain words. The small, healthy change in time between heartbeats. It reflects how your nervous system balances fight or flight with rest and digest, and low variability can mean there is little reserve. It is a measurement, not a diagnosis, and not a condition in itself. What the research on heart rate variability looked at.

traveling for care

Coming from another state, or hours away?

People drive from across Michigan because nothing closer worked. If you live hours away, or in another state, working out the days, the hotel and the records shouldn't be yours to carry alone. Our office is at 203 S. Zeeb Rd, Ann Arbor, Michigan.

What kind of doctor should I see for dysautonomia or POTS?

Start with your medical doctor and, often, a cardiologist or neurologist who knows autonomic disorders, because some causes need medical care. Many people still end up with normal results and no plan. We are not POTS specialists. We measure how your nervous system is regulating your body, and we look at the upper neck.

Is there research on upper cervical care for POTS?

Not on POTS or dysautonomia directly. We haven't found a verified upper cervical study on either. The closest research measured heart rate variability and blood pressure, which the autonomic nervous system controls, and even there the results are mixed. We would rather say that plainly than borrow a result that doesn't apply.

What is heart rate variability?

Heart rate variability is the small, healthy change in time between heartbeats. It reflects how your nervous system balances fight or flight with rest and digest. Low variability can mean the system has little reserve. It is a measurement, not a diagnosis, and it is one of the scans we take before any correction.

Is it just anxiety?

Anxiety is real, and so is a nervous system stuck in fight or flight. When heart and blood tests come back normal, the label often becomes anxiety without anyone measuring how the autonomic system is regulating. Measuring it doesn't dismiss either possibility. It gives you and your doctors something more to go on.
