— The Unsolved Cases

Every Medical Professional Has the Patients They Could Not Close the Loop On

The POTS case that bounced between cardiology and psychiatry. The Long-COVID or PTSD patient whose labs come back normal while the symptoms stay real. The patient who has already seen everyone and tells you so.

Those visits cost time, and they leave without an answer or a follow-up. Autonomic dysfunction affects an estimated 90 million people, and most of it is never measured. When you can measure it, the unsolved case becomes a solved one, and a referral source.

  • POTS, differentiated from syncope by the direction of the sympathetic response to standing

  • Long-COVID, with the autonomic component quantified when standard testing reads normal

    PTSD, where the quality-of-life symptoms are autonomic and therefore measurable

  • Forty-three conditions in total, each with the parasympathetic or sympathetic pattern behind it

— Clinical impact

50+ Conditions. One Platform.

ANS testing provides physicians with actionable data across an unprecedented spectrum of diseases and disorders, many of which go undetected by standard diagnostic methods.

Clinical Monitoring Unit (CMU)

The Clinical Monitoring Unit is a desktop-based ANS monitoring system designed for any clinic environment. FDA 510(k) cleared and supported by fundable billing codes, the CMU gives your practice a deeper look at autonomic function, while opening a new, supportable revenue stream.

ANS Monitoring Integration

ANS monitoring integration from Physio PS helps medical practices add autonomic function testing to existing treatment protocols, with automated workflows, patient-facing reports, and clinical guidance included. No complex setup, no steep learning curve, and potential for cash-based add-on services

Remote Monitoring Unit (RMU)

The Remote Monitoring Unit is a portable, tablet-based ANS monitoring system built for in-home care providers and sports medicine practitioners. Battery-powered and compact, it brings the same complete autonomic function testing to any setting, without being tethered to a clinic.

Portable Autonomic Lab (PAL)

The Portable Autonomic Lab is a laptop-based ANS monitoring solution built for the medical professional who moves between facilities or works in the field. Multiple power options and a compact form factor mean you get complete autonomic function testing wherever the work takes you.

Research Software Program (Physio PS 4.0)

Physio PS 4.0 is a research-grade ANS software program available to approved researchers on a one-year renewable license. Built on the same platform trusted by physicians worldwide, it gives research teams the autonomic monitoring tools needed for rigorous, publishable work.

— The Clinical Case

Where Heart Rate Variability Stops Short

Most autonomic tools report a single blended figure, or measure the sympathetic branch alone. Heart rate variability tells you something is off without telling you which branch is driving it, and most drugs and diseases affect only one of the two.

P&S monitoring resolves both branches independently and simultaneously, so the question moves from how active the system is to how the two sides relate. In cardiology that distinction decides therapy.

  • Roughly 80% of atrial dysrhythmias involve the P&S systems; monitoring specifies which branch, rather than treating all of them as cardiogenic

  • Congestive heart failure shows a rising sympathetic baseline up to four days before the 3% weight-gain indicator, leaving room for a temporary diuretic increase instead of a hospitalisation

  • Vasovagal, neurogenic and cardiogenic syncope separate on the stand response, where tilt-table struggles to differentiate

  • Cardiovascular autonomic neuropathy is identified early, when the mortality risk is still modifiable

— CONDITIONS

Cardiology Conditions Where Both Branches Matter

Each entry notes the parasympathetic or sympathetic pattern that monitoring resolves.

  • Hypertension

    Typically characterised by sympathetic excess driving up the baroreceptor reflex, beginning with a decline in resting parasympathetic activity.

  • Cardiac Dysrhythmias
    About 80% of atrial dysrhythmias involve the P&S systems; only 20% are purely cardiogenic.

  • POTS

    The sympathetic response to standing is quantified, differentiating orthostatic dysfunction from syncope.

  • Cardiomyopathy
    Characterised by sympathetic excess; forms may turn symptomatic when orthostatic dysfunction or syncope appears.

  • Congestive Heart Failure

    High sympathetic baseline precedes even the 3% weight-gain indicator, by up to four days.

  • Syncope and Collapse
    Monitoring positively identifies vasovagal and neurogenic syncope and separates the neuro component from the cardio.

  • Angina

    A function of sympathetic excess, from excess vasoconstriction or atherosclerotic build-up.

  • Post-MI
    Myocardial infarction causes sympathetic excess, and post-MI symptoms follow from it.

— In the Room

What the Visit Looks Like

Patient seated, leads placed

A heart rate monitor, ECG leads and a blood pressure cuff. Nothing invasive, no tilt table.

Fifteen minutes of recording

Resting baseline, then a short series of standard challenges: paced breathing, Valsalva, and a head-up postural change.

Both branches resolved separately

The software measures RFa and LFa, giving parasympathetic and sympathetic activity as two independent readings.

Report before the patient leaves

Qualitative, quantitative and graphical output, ready for your review and for the patient to take home.

— Billing and Setup

Supported by Fundable Billing Codes

The assessment is supported by fundable billing codes, adding a documented revenue stream to your practice without adding staff burden.

Training and certification are included, so your team is ready from day one.

Ask about billing code applicability for your specialty during your demo.

✓ FDA 510(k) Cleared

✓ Patented Technology

✓ Backed by Published Research

— FAQ

Questions Practices Ask Before They Start

Straight answers on time, cost, clearance and fit.

How long does an assessment take?

A complete autonomic assessment is non-invasive and takes 15 minutes. It is fully automated, and the qualitative, quantitative and graphical reports are delivered without manual interpretation.

Is the technology FDA cleared?

Yes. The platform is FDA 510(k) cleared to U.S. medical device standards, patented, and backed by published research.

How is testing paid for?

The Clinical Monitoring Unit is supported by fundable billing codes. For the other systems, ask about billing code applicability during your demo. Financing options, low monthly payments and veteran-owned discounts are available to qualifying practices.

Do we need extra staff, space or a tilt table?

No. Testing integrates with your existing treatment protocols with no workflow overhaul and no tilt table required. Training and certification are included, so your team is ready from day one.

How is this different from heart rate variability tools?

It is the only solution on the market that measures both parasympathetic and sympathetic branches independently, simultaneously and quantitatively, rather than reporting one blended figure.

Which system fits my practice?

The CMU is a desktop system for clinics, the RMU is tablet-based and battery-powered for home care and sports medicine, and the PAL is laptop-based for medical professionals who move between facilities. A free demo is the quickest way to find the right configuration.

How do I become a distributor?

Tell us about your territory and the clinics you work with through the distributor enquiry form, or call 603-287-1817, and the team will follow up to discuss distribution.
