How artificial intelligence helps people with atrial fibrillation

This small device may change how doctors identify and manage patients with atrial fibrillation  an irregular heart rhythm that increases risk of stroke.

And the past. The device uses artificial intelligence, or AI, to not only determine if a person is in the midst of an episode of atrial fibrillation, but also it can reveal if they've had the irregular rhythm before or will have it in the future.

Dr. Paul Friedman and his team trained the device to detect subtle changes in the heart’s electrical signals. Then in a study, they found it can identify patients with episodic atrial fibrillation. Even when they record the heart while the rhythm is normal – something no current wearable heart monitor can do.

That's because a heart monitor won't detect atrial fibrillation unless you have an episode while wearing it. But in a matter of moments, the AI device can identify people with atrial fibrillation, even if their heart is in normal rhythm. Then they can get on the right treatment to help prevent life-threatening strokes from happening.
