Apple Watch can detect early signs of a stroke using AI

I bet your doctor doesn't suggest you use this to detect atrial fibrillation. So don't diagnose yourself with AF before your doctor does. Wrong title, it might detect signs of a risk for stroke. The president of our great stroke association would be contacting the reporter on this and getting the headline corrected.

The Apple Watch could save lives by spotting early signs of a stroke, according to new research.

When paired with AI algorithms, the smartwatch can detect atrial fibrillation – the most common form of an irregular heartbeat – 97 per cent of the time, according to a study from app maker Cardiogram and UCSF Health lab.

Atrial fibrillation is the cause of one in four strokes, so it’s hoped that the smartwatch software could eventually help to prevent strokes happening in the first place.

In the study, data from 6,158 users of the Apple Watch Cardiogram app, including 200 participants with atrial fibrillation, was used to train a neural network on the watch’s heart rate readings, .

The software was trained to tell the difference between those with the heart condition and those without.
