Apple Watch, and other consumer wearables including Android Wear devices, were used in a study that applies a neural network called DeepHeart to recorded heart rate data in a bid to detect atrial fibrillation, a common heart arrhythmia that can lead to stroke in some patients.
As AppleInsider detailed last May, the DeepHeart study is a joint effort between the University of California, San Francisco’s Health eHearth Study and digital health startup Cardiogram, the latter of which markets an eponymous Apple Watch app.
