The aim of the study is to evaluate the performance of Withings SCT02 with embedded Withings ECG-app in the automatic detection of atrial fibrillation

• Subject able to read, understand, and provide written informed consent
• Subject willing and able to participate in the study procedures as described in the consent form
• Subject able to communicate effectively with and willing to follow instructions from the study staff

Exclusion Criteria:

• Subject with an implanted electrical device (i.e. pacemaker, ICD …), whether active or inactive

• Active or history of life-threatening rhythms as determined by investigators (e.g. ventricular tachycardia, ventricular fibrillation, 3rd degree heart block)
• Any cardiovascular disease that investigators would consider as a risk to subject or renders data uninterpretable (e.g. recent or ongoing unstable angina, decompensated heart failure, active myocarditis or pericarditis)
• Active or symptomatic skin disease on Schiller electrode attachment sites or fingertips which would be in contact with BeamO electrodes (e.g. eczema, rosacea, impetigo, dermatomyositis or allergic contact dermatitis)
• Known sensitivity to medical adhesives, isopropyl alcohol,, electrocardiogram (ECG) electrodes, including known allergy or sensitivity to stainless steel (used in BeamO electrodes).
