> Artificial intelligence can predict a person’s chances of dying within a year by looking at heart test results – even when they look normal to doctors. How it does so is a mystery.

Brandon Fornwalt at healthcare provider Geisinger in Pennsylvania, US and colleagues tasked an AI with examining 1.77 million electrocardiogram (ECG) results from nearly 400,000 people to predict who was at a higher risk of dying within the next year.

An ECG records the electrical activity of the heart. Its pattern changes in cardiac conditions including heart attacks and atrial fibrillation.
