Superhuman AI Spots Heart Disease in Under 2 Seconds

Doctors have created an AI tool that can detect heart disease in less than two seconds—faster and more accurately than the human eye. The system, described as “superhuman,” was trained on millions of routine electrocardiograms (ECGs), which record the heart’s electrical activity. It works by pulling out subtle patterns from these tests that standard human analysis often misses. In practice, this means high-risk patients could be identified and referred for treatment much sooner, without waiting for a specialist’s review. The technology is not meant to replace doctors, but to speed up and sharpen the first step of heart care. The breakthrough comes from researchers who say the AI has effectively learned to see beyond what a trained cardiologist can observe in a standard ECG. While the tool is still in its early clinical stages, its speed and precision could make it a routine part of hospital screening in the near future. For now, the promise is clear: a heart problem that might take minutes to spot—or go unnoticed—can now be flagged in the blink of an eye.
