Sponsor's own description

Atrial fibrillation (AF) is the most common cardiac arrhythmia. This study is to assess the heart rhythm device accuracy of five cardiac wearable devices (Apple Watch, Kardia Mobile/Kardia Mobile 6L, Fitbit Sense, Samsung Galaxy Watch 3 and Withings Scanwatch, Withings SA, Model Number: HWA09) and its detection algorithms in identifying AF compared to a nearly simultaneously acquired physician-interpreted 12-lead ECG in a real world cohort of patients.
