ECG Reader

Coming soon · Android

Clinical decision support for reading paper ECGs · for qualified clinicians

In many hospitals and clinics the ECG is still a paper print. ECG Reader lets a clinician photograph a printed 12-lead ECG or rhythm strip and get a structured reading, with an alert level that flags patterns that may need urgent action.

Decision support only. ECG Reader does not diagnose. It can be wrong, including missing a dangerous pattern. Always read the ECG yourself; your own judgment prevails. Read the full disclaimer.

How it works

Photograph or choose the ECG. Lay it flat in even light. The app warns about blur, glare and darkness.
Crop to the trace. Remove the printed header, so the patient's name and ID are not sent. Photo metadata (location, device, time) is removed on the phone.
Reading. An AI vision model describes the trace in a fixed structure: rate, rhythm, intervals, axis, and findings with leads and confidence.
Alert level. A fixed, clinician-reviewed rule table — not the AI — turns that description into an alert level, with the reasons shown.
Optional clinical context. Add symptoms, blood pressure, heart rate or SpO₂. These can only raise the alert level, never lower it.

Alert levels

Critical — pattern consistent with an immediate life threat.

Urgent — significant abnormality needing prompt review.

Abnormal — abnormal, but not time-critical on this image alone.

No critical pattern seen — nothing alarming was detected. This is not a statement that the ECG is normal.

Unreadable — the image cannot be read reliably; retake it.

Privacy in one line

No account, no history, no analytics: the image and the result are not stored by the app or by our server. See the privacy policy.

Validation and limits

Before release, the reading engine is tested on reference ECGs with cardiologist labels (PTB-XL, PhysioNet), and on realistic phone-photo versions of them. Detecting critical patterns is measured first.
Some patterns are rare in reference data. They are tested separately before the critical list is signed off.
A single image can miss intermittent or evolving changes. Compare with previous ECGs and repeat the ECG when the clinical picture changes.
The app reads only what is printed. Poor photos, faded thermal paper, unusual layouts and cropped leads reduce accuracy.

Availability

ECG Reader is being validated now. It will first go to a small group of doctors through Google Play closed testing. If you would like to take part, email homilabs.smc@gmail.com.
