How accurate is smartphone-based cardiac scanning?

Sonus Health uses advanced signal processing and machine learning to extract heart sounds from smartphone recordings with clinical-grade fidelity. Every full analysis is reviewed by a board-certified veterinary cardiologist, providing clinical insight comparable to specialist auscultation. Instant preliminary results provide a reliable initial screening, supported by our research.

What species does Sonus Health support?

Sonus Health supports dogs and cats, with horses now available in beta. Our models are trained on large, species-specific cardiac datasets to account for differences in heart rate, anatomy, and acoustic profiles.

How quickly will I receive results?

AI-derived metrics such as heart rate, HRV, and murmur detection are available within seconds of recording. Cardiologist-reviewed reports are typically returned within 24 hours for 95% of submissions.

What's included in a Sonus Health report?

Before requesting a cardiologist report or veterinary review, every scan instantly shows preliminary results such as heart rate, heart rate variability, and indications of a possible murmur.A full cardiologist report includes confirmation or exclusion of a murmur, along with assessment of heart sounds and rhythm, including detection of gallop sounds and arrhythmias, and other clinically relevant findings identifiable on auscultation. It also includes a narrative clinical interpretation and guidance on potential next steps.

Free scans and a report are included on signup, with no credit card required. Clinics can place patients on monitoring plans according to clinical need, or use flexible credit bundles for ongoing access. Owners not linked to a clinic can also subscribe monthly, with additional cardiologist reports available as needed. Volume pricing is available for larger practices.

How do I scan my pet?

Place any smartphone against the animal's chest, no accessories needed. Record for at least 20 seconds in a quiet environment. For detailed species-specific instructions and a video guide, visit our how to scan page.

Better outcomes New revenue

Cardiac care that extends beyond the consulting room.

The Sonus Health app fills the gap between routine auscultation and expensive cardiac escalation. It gives clinics longitudinal heart and respiratory monitoring, plus a new line of recurring revenue, right where one didn't exist before.

01 The gap

There has never been anything between the stethoscope and the specialist.

A ten-minute consultation once a year, a stethoscope, a hunch. If anything sounds off, a referral: weeks of waiting, hundreds of pounds, a stressed animal, and a conversation the owner may or may not agree to. In between, silence.

Bella's Heart Scan Report

9yo Female Cavalier King Charles Spaniel · 15/03/2026

At a Glance

HR118 bpm

HRV34 (RMSSD)

MurmurSoft systolic murmur detected

ArrhythmiaNo indications detected

Other PathologiesNo indications detected

Overall Conclusion

We have identified a soft systolic heart murmur on the left side of the chest. The heart rate is mildly elevated at 118 bpm, which may reflect mild anxiety during the recording or early compensatory changes. Heart rate variability is within an acceptable range. Given the breed predisposition of Cavalier King Charles Spaniels to myxomatous mitral valve disease (MMVD), we recommend an echocardiographic evaluation to assess the mitral valve structure and any associated chamber enlargement.

In Depth

This is a cardiac wellness assessment of Bella, a 9-year-old female Cavalier King Charles Spaniel. The recording was obtained via the Sonus Health smartphone application and has been reviewed by a veterinary cardiologist.

Track 01 Outcomes

The conditions a ten-minute consultation might miss.

Heart disease isn't episodic. It progresses between appointments, quietly. Sonus Health lets clinicians watch the heart the way they always wanted to: week over week, at home, with the owner looking on.

Case · MMVD early detection

Luna

Cocker Spaniel · 9

Scans: 14 · Duration: 11 months · Specialist escalations: 1

Luna's stethoscope exam was unremarkable at her annual check. But her owner had been running a monthly Sonus Health scan at home. On the May recording, something subtle had shifted in the mitral valve sound. A diplomate cardiologist reviewed the file the same week and confirmed early-stage MMVD. Treatment began fourteen months earlier than it would have otherwise. Luna is still competing in agility trials.

"Getting a second opinion from a diplomate cardiologist, without the wait and stress of a referral, is a game-changer for how we manage cardiac patients."

Dr Laurent Locquet, Dipl. ECVIM-CA (Cardiology)

Owner engagement: 4× more monitoring touchpoints per year vs. annual-exam only
Time to specialist: 24h from flag to diplomate report, for 95% of cases

What this changes

See the heart over time, not just in a ten-minute appointment.

Monthly at-home scans produce a timeline where episodic exams produce snapshots. Progression becomes visible before symptoms do.

Catch murmurs your stethoscope might miss.

Digital auscultation detects subtle murmurs missed in consult-room conditions, validated against diplomate cardiology reads.

Give owners a reason to stay engaged between visits.

Monitoring becomes something the owner does with their vet, not something they forget about until next year's renewal.

Track 02 Economics

A new line of revenue, in a gap that didn't exist before.

Sonus Health Care Plans aren't a new version of something a clinic already sells. They are a service only possible because Sonus Health exists, and they are built to carry a meaningful clinic margin by design.

Illustrative unit economics. Actual margin varies with local pricing, Sonus Health volume tier, and whether the clinic delivers the scan in-clinic or enables the owner to scan at home.

Clinic margin, by design

30–50%

Baked into the suggested retail price of every Care Plan. Not a bonus. Not a bolt-on. The economic model of the product.

Unlike tests a clinic already sells at razor-thin margins, Care Plans were designed from the first day to carry clinic margin. The product only exists if clinics are the ones delivering it.

03 If you're the one bringing this in

You've seen the case.
Here's what you need to make it.

Most vets who bring Sonus Health into their clinic aren't the owner. They're the clinician who read about it, watched a demo, and has to walk next door and make the case to the person who signs the invoice. So here's the case, in their language.

Asset 01 · The 90-second pitch

Hi [Practice Owner],

I've been looking at Sonus Health. It's a smartphone-based cardiac screening and monitoring tool. Thirty-second scan, AI-driven HR/HRV/murmur detection, specialist review on demand.

What's different: it fills the space between the stethoscope and the specialist. We don't currently offer anything there. Owners either wait until symptoms force a referral, or they don't come in at all. With Sonus Health, we can sell longitudinal Care Plans (annual scans, medication follow-up, post-diagnosis monitoring) at a 30–50% clinic margin. Real revenue, from a service we literally couldn't offer before.

They offer free scans and a report on signup, with no credit card required. I'd like to register the clinic and try it on my next few senior consults. Once we've got a handful of data points, I'll walk you through what we're seeing.

Sonus has enabled earlier identification of cardiac conditions and supports consistent monitoring both in-clinic and at home. The reports are accurate, professional, and integrate seamlessly into our clinical workflow, providing clear evidence to support discussions with owners around further diagnostics such as echocardiography.
