Deep CNN Enables Robust Atrial Fibrillation Detection from Wrist PPG in Free-Living Conditions
Researchers developed a 50-layer CNN to detect atrial fibrillation (AF) episodes from wrist-worn PPG signals in ambulatory settings. They annotated a new dataset of over 4000 hours of PPG data, achieving 95% test AUC despite motion artifacts. This advances wearable devices toward clinical-grade AF m…
