AI Tool Detects Heart Disease in 2 Seconds From ECGs, Identifying Up to 90%
3 articles · Updated · The Guardian · Aug 31
Summary
A new AI system can flag heart failure and heart valve disease from a routine ECG in under two seconds, offering a rapid triage tool rather than a standalone diagnosis.
In a 67,000-patient US trial, it identified up to 81% of people with heart failure and up to 90% with heart valve disease after being trained on millions of patients.
The technology matters because ECGs are widely available while echocardiograms—the scans needed to confirm disease—can take months, allowing high-risk patients to be moved up waiting lists sooner.
Because about 1 billion ECGs are performed worldwide each year, the tool could also be run across hospital ECGs to catch unsuspected cases earlier and start treatment faster.

2026’s AI ECG Revolution: Superhuman Detection, Wearable Integration, and the New Era of Cardiovascular Medicine
Overview
In August 2026, researchers unveiled a superhuman AI ECG tool that can detect heart disease in under two seconds by extracting hidden patterns from standard ECGs. This innovation transforms routine ECGs into powerful early-detection tools, flagging heart failure and valve disease before symptoms appear, allowing clinicians to intervene early and prevent late-stage crises. Integrated into standard workflows, the AI acts as a gatekeeper, rapidly identifying high-risk patients for urgent imaging and fast-tracking their care. Supported by national initiatives and clinician-centered dashboards, these AI tools help manage patient backlogs, reduce clinician burnout, and make massive streams of health data manageable and actionable.
