Actual (reported)Correct detection of AF
Sensitivity and specificity of the Preventicus Heartbeats App to distinguish between AF and SR
5 minutes
Differences in correct detection of AF between Smartwatch and Wristband
5 minutes
Reduced sensitivity and specificity in patients with >2% premature beats
5 minutes
Five minutes pulse wave recording in patients with atrial fibrillation at the time of recruitment
Five minutes pulse wave recording in patients with sinus rhythm at the time of recruitment
Patients will wear a smart watch and a wristband each at one arm. A standard egg (lead I) and pig signals from the wearables will be recorded for five minutes.
