Figure 2. The Study Watch is a prescription device connected to an end‐to‐end system that includes real‐time prompts for a user to record a single‐lead ECG when AF is suspected by the on‐watch PPG algorithm.

The acquired ECGs are transmitted to a cloud server where automated rhythm classification is reviewed by human experts. Only validated findings are then shared with the prescribing physician through reports. CCTs indicates certified cardiographic technicians; HCP, health care provider; and PPG, photoplethysmography.
