Conditions

Atrial Fibrillation

Brief summary

This is a prospective, non-randomized study to refine the Study Watch's algorithm for AF detection within both persistent and paroxysmal AF subjects. The study will also collect data from an FDA-cleared wearable ECG sensor.

Interventions

Study Watch is a miniaturized physiological data monitoring and data collection device for continuous recording of physiological and environmental data
