‘Superhuman’ AI tool spots heart disease in less than 2 seconds
Researchers have developed an AI tool that analyzes routine ECG data to detect heart disease in under two seconds, drawing on training from millions of patient records. The system is designed to identify patterns beyond what clinicians can observe visually, potentially accelerating care for high-risk patients.
Why this matters: The clinical upside here is real. Faster, more accurate cardiac screening could get people into treatment before a serious event. But a tool trained on millions of ECGs also means millions of people's sensitive health data fed into a system, and that data trail matters. Who holds it, who can access it, and what else it gets used for are not settled questions. Medical AI that works well on average can still fail specific groups. Knowing a tool is fast is not the same as knowing it is safe for everyone.
