Determine AF Burden With PPG Trial - Detection and Quantification of Episodes of Atrial Fibrillation

Participants will then receive a PPG sensor in form of a smartwatch) model and will be instructed to wear them continuously for 48 hours. Simultaneously, a 48-hour Holter ECG will be performed. Start time on the PPG-sensor and the Holter ECG will be matched and continuous heart rhythm and -rate monitoring will be initiated. Patients will wear the devices over a 48-hour period of time.
