One ECG.
Four applications.

A short, easy-to-capture Lead I ECG, read by purpose-built AI models. Each has been developed based on over a decade of experience, a proprietary corpus of physician-annotated ECG data, and multiple clinical research partnerships.

Diagram: a single ECG waveform branching into four labeled applications — heart failure risk, atrial fibrillation risk, stress, and ECG authentication.

Applications

Heart failure risk identification and atrial fibrillation identification are both trained to identify heart abnormalities from ECG.
ECG Authentication and Stress Index apply that same single-lead ECG to entirely different purposes, from identity to stress.

Heart failure risk identification

Investigational

A software-only assessment of heart-failure risk from a single Lead I ECG, for early identification in clinic and ongoing monitoring. Designed to help identify heart-failure risk independent of ejection fraction, including HFpEF.

Atrial fibrillation identification

Investigational

Extending single-lead ECG analysis into atrial fibrillation.

Research pipeline

ECG Authentication

An AI that authenticates individuals using the unique characteristics contained in their ECG. Unlike static biometric data such as fingerprints or veins, ECG data changes over time, so authentication accuracy is maintained through continuous data updates and time-course analysis. Developed with a US-patented method from our collaboration with the University of Aizu.

Stress Index

An AI that estimates and quantifies stress levels from ECG or pulse signals. From a 30-second ECG recording, it analyzes heart-rate variability across the time-domain, frequency-domain, and non-linear domains, combining them into a single stress index.

Architecture

To analyze a Lead I ECG reliably, we evaluate and reduce noise with proprietary filters before it reaches the AI.

Input
ECG waveform
A short resting Lead I ECG, compatible with standard clinical ECG devices and wearables.
Preprocessing
Noise filter
ECGs recorded at home carry noise patterns that hospital-grade recordings don't. Each waveform is evaluated and denoised before it reaches the AI.
AI
SQ Library
We build a dedicated model for each of the four applications, trained and validated with its own methodology.
Outputs
Clinical indices & reference information
Each application outputs statistical indices and reference information suited to its use case, customizable to the deployment environment.
