We understand

The problem you know too well

If you're here, you've probably been on a long, frustrating journey. You know something is wrong with your body. We believe you.

4.5 years

Average time to diagnosis

Nearly half a decade of appointments, tests, and uncertainty before most dysautonomia patients finally get an answer. That is not acceptable.

"Just anxiety"

The most common misdiagnosis

You know the feeling. Your heart is racing, you can barely stand, and your doctor says it is stress. Your symptoms are real, and they deserve real investigation.

Questionnaires

Self-reported screening that misses real conditions

Most initial screening relies on you describing your own symptoms. But dysautonomia is physiological -- it shows up in your heart rate, blood pressure, and nervous system data. Subjective forms miss what objective data catches.

6-18 months

Waitlists at specialized centers

Even if your doctor believes you, the few dysautonomia centers in the country are overwhelmed. Half a year to a year and a half of waiting, while your life stays on hold.

"We built Zebra because we have lived this. The diagnostic odyssey should not define your experience. You deserve answers that start with real data, not more waiting."

Your choice

Two paths forward

However you want to move forward, Zebra gives you the objective data you need. Choose the path that fits your situation.

A

Screen & Bring to Your Clinician

Do the testing at home on your own schedule. Get a clinical-grade report packed with objective data. Then bring it to your existing doctor and change the conversation.

  • HRV data and orthostatic response metrics
  • 17 temporal dynamics features analyzed
  • Stop relying on symptom diaries alone
  • Give your clinician something concrete and objective
B

Get Matched with a Dysautonomia Center

Use Zebra's concierge referral to get fast-tracked into a specialized dysautonomia center. We pre-screen you, build your data package, and help get you prioritized admission.

  • Pre-screening with objective data before referral
  • Complete data package built for you
  • Skip the 6-18 month waitlist
  • Matched to a center that specializes in your condition
Simple process

How it works

Four simple steps from your couch to clinical-grade answers. No clinic visits, no long waitlists, no guesswork.

1

Connect your wearable

Polar H10, Apple Watch, Oura Ring, Garmin, or Fitbit. Use the device you already own.

2

Complete guided protocols

Orthostatic challenge · 25 min
Extended standing · 35 min
Valsalva maneuver · 20 min

Safe, simple, and app-guided. Done from the comfort of your home.

3

Get your results

HR increase, BP changes, HRV analysis, 17 temporal dynamics features, and POTS subtype probability -- all in a clear, shareable report.

4

Take action

Bring your clinical-grade report to your doctor, or let us match you with a specialized dysautonomia center. Your data, your choice.

Detection

What we detect

Zebra screens for a range of autonomic dysfunction markers using real physiological data from your wearable.

POTS Subtype Classification

Hyperadrenergic, neuropathic, and hypovolemic subtypes -- identified through your heart rate and autonomic response patterns.

Orthostatic Hypotension

Blood pressure drops on standing detected through cardiovascular response analysis during postural challenges.

Baroreflex Dysfunction

Abnormalities in the blood pressure regulation feedback loop, revealed through Valsalva maneuver phase analysis.

Sympathetic Vasoconstriction Patterns

Abnormal sympathetic nervous system responses that affect blood vessel constriction during positional changes.

Vagal Reactivation Abnormalities

Delayed or impaired parasympathetic recovery after physiological stress, a key indicator of autonomic dysfunction.

Heart Rate Variability Anomalies

Reduced or abnormal HRV patterns that signal autonomic nervous system imbalance, analyzed across time and frequency domains.

Your data is yours

Clinical-grade screening, patient-owned results. We built Zebra with your privacy as a non-negotiable foundation.

HIPAA Compliant

Your health data is protected by the highest standard of healthcare privacy regulations.

Your data is never sold

We do not sell, share, or monetize your health data. Period. That is a promise, not a policy footnote.

You control who sees your results

Share your report with your doctor, a specialist, or no one at all. You decide who gets access.

Clinical-grade but patient-owned

The same rigor as a hospital test, but you hold the results. Download, print, or share on your terms.
