What Makes Cardio-HART Different?

More Than an ECG—Much More

Cardio-HART is a next-generation ECG device that combines novel biosignals—heart sounds (PCG) and chest wall motion (MCG)—with advanced AI to deliver diagnostic capabilities equivalent to an ECG, digital stethoscope, and echocardiogram—all in a single, ECG-like test.

Cardio – HART report includes ECG + Echo-like data.

What this delivers:

Detection of HF, HFpEF, valve disease, and structural heart anomalies
Simpson Biplane levels of LVEF estimation and HF scoring
Severity information, on Echo and ECG findings
Structured reports, readable by any clinician—no specialist required

It’s ECG redefined—with real-time, echo-grade answers at the point of care.

What Happened When HCPs Faced Real Diagnostic Challenges

🧪
Study Methodology

Venue: 3 cardiology conferences (2024–2025)

London Diabetes & Cardiology Show, London Heart Failure Show, Seville Cardiology Congress

Use Case: Two inconclusive ECG cases common in GP practice
Data Provided:
- ECG-only: Traces, AI Findings, Measurements
- Cardio-HART: Full CHART Report including ECG + Echo-like data

ECG vs Cardio-HART AI heart diagnostic report comparison

Doctors reviewing ECG and Cardio-HART AI heart diagnostic reports in 2-step protocol

🔁 Two-Step Survey Protocol

Step 1: Using only ECG

Doctors had 5 minutes per case to:

Review the ECG, traces, findings and measurements
Make a diagnosis
Decision: refer to cardiology or treat in clinic

Step 2: Cardio-HART Review

Then, they received the Cardio-HART AI heart diagnostic report for the same case and could revise their decision.

Results

Step 1 – ECG-Only Results

~65% got both cases wrong

~5% got both cases right

~20% got 1 out of 2 right (mostly guessed)

~10% refused to answer

Diagnostic confidence was extremely low

Step 2 – With Cardio-HART

65% initially wrong — all changed their diagnosis and decision after Cardio-HART.

20% guessed 1 right — all revised their diagnosis and decision after Cardio-HART.

5% with both right — all impressed Cardio-HART added clarity to their diagnosis and decision.

100% reached 100% diagnostic certainty after Cardio-HART.

100% saw the risk of inconclusive ECGs and the value of Cardio-HART insights.

100% agreed, Cardio-HART was a game changer

100% agreed, Cardio-HART is not a replacement for Echo, but an upgrade for ECG.

It get clear answers—fast! That’s why I replaced my standard ECG with Cardio-HART AI heart diagnostic. It gives me everything a standard ECG does, plus it adds echo-level insights–in minutes—helping me detect early signs of heart failure or valve disease so I can take action right away.

If NHS adopted Cardio-HART at scale, we’d ease pressure on hospital echo departments and make faster, better-informed decisions for patients.

Prevention Begins at First Contact

Early Detection = Early Treatment

Cardio-HART AI heart diagnostic detects cardiac disease before symptoms escalate. Stop disease progression. Start treatment sooner.

GP-Level Power, Specialist-Grade Insight

What once required a referral to hospital for echocardiography
can now happen in less than 10 minutes, at point of first contact.

Beyond Biomarkers

NT-proBNP is useful but underused and limited—its false positive rate is~50%¹.
Cardio-HART not only confirms when NT-proBNP should be ordered, it offers on the spot physiological evidence of all three types of HF, with a Positive Predictive Value (PPV) of over 90%.

Millions Could Benefit

Earlier intervention. Fewer hospitalisations. Better patient outcomes—closer to home.

Instant Insights: Your Top Questions

For GPs

How does Cardio-HART help diagnose heart disease earlier?

Cardio-HART AI heart diagnostic gives GPs a way to detect heart conditions in about 10 minutes — during a routine appointment. It enhances a standard ECG with echocardiography-like insights, allowing GPs to catch heart failure, valve disease, and other conditions much sooner.

What makes Cardio-HART better than an ECG?

ECG only shows electrical activity. Cardio-HART analyses electrical signals and mechanical function of the heart — like a virtual echocardiogram — providing evidence of structural and functional abnormalities that ECG alone cannot detect, dramatically reducing inconclusive ECGs.

Does Cardio-HART integrate into my practice workflow?

Yes, Cardio-HART is a direct replacement for ECG and fits seamlessly into current workflows. Results can be easily shared, supporting remote review and collaborative decision-making between GPs and cardiologists.

For Cardiologists

How does Cardio-HART improve referrals?

Cardio-HART improves referral quality by providing objective evidence of cardiac dysfunction from primary care. Cardiologists receive patients with confirmed abnormalities, reducing low-yield referrals and focusing resources on those who truly need specialist care.

Can Cardio-HART replace echocardiography?

No — Cardio-HART complements echocardiography. It is not a replacement for echocardiography but rather a powerful triage tool for earlier detection that bridges the gap between the capabilities of ECG used in primary care and of echocardiography, available only in secondary care.

What value does Cardio-HART bring to secondary care?

Pre-referral evidence for faster triage
Reduced diagnostic backlog
Better prioritization of urgent cases
Improved patient pathways from primary to secondary care

For Patients

What will I experience during a Cardio-HART test?

The experience is very similar to a standard ECG. You’ll be asked to lie down comfortably on an exam table. The test lasts about 10-15 minutes, and the results are available immediately.

Is Cardio-HART safe?

Yes, Cardio-HART is completely safe. It is a non-invasive test, which means nothing goes inside your body. It’s as safe as having your blood pressure checked or an ECG.

How is Cardio-HART different from other heart tests my doctor could send me for?

Cardio-HART is unique because it combines ECG, heart sound analysis, and AI-based insights, providing much more information in a single test compared to a standard ECG, which only checks electrical activity.

For Commissioners

How immediate are the benefits?

Instant. Cardio‑HART delivers measurable impact from the very first patient visit. It immediately reduces unnecessary echo referrals and prevents avoidable emergency admissions by enabling in‑clinic detection, easing both hospital burden and system costs.

How expensive is the device? Can it scale?

Cardio‑HART costs less than many brand‑name ECG devices while providing echo‑level insights. It requires no specialist to operate or interpret results, making it a direct ECG replacement that scales seamlessly across primary care and regional healthcare systems.

Does it align with healthcare priorities?

Yes. Cardio‑HART supports early diagnosis, reduces low‑value testing, and promotes equitable access to cardiac care while cutting costs and hospital demand. It even supports NHS Net Zero goals by reducing patient travel and imaging emissions.
