TL;DR
Meeting abstract. Retrievable text gives the motivation only: AF management is moving from binary detection to AF burden (guides anticoagulation duration and post-ablation surveillance); consumer watches collect continuous PPG plus intermittent ECG but report only binary alerts, and no deployed method yields a continuous ECG-validated AF burden. The title states the tool is an ECG-distilled deep foundation model applied to watch PPG.

Abstract
AF management is shifting from binary detection to AF burden, which guides anticoagulation duration and post-ablation surveillance. Consumer watches collect continuous PPG and intermittent ECG but report only binary alerts; no deployed method yields a continuous, ECG-validated AF burden.
