- Subject mentally impaired resulting in limited ability to cooperate
- Subject with a pacemaker, ICD (Implantable cardioverter defibrillator) or other implanted electronic stimulator

- Acute pulmonary embolism or pulmonary infarction, within 90 days of screening
- Stroke or transient ischemic attack within 90 days of screening

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Withings WBS08 and 12-lead reference ECG
Arm Description
The electrodes of the 12-lead ECG will be set up on the participants, before they step on withings WBS08 to have ECGs simultaneously recorded by the study device and the control device
Outcomes
Primary Outcome Measures
Performance in the identification of atrial fibrillation and sinus rhythm
The co-primary endpoints are the sensitivity and specificity in detecting AF from conclusive recordings generated by the software under test, that is recordings resulting in a classification of AF or SR by the SUT, compared to the reference 12-lead ECG.
Secondary Outcome Measures
Evaluation of the classification into heart rate subgroups
The classification into heart rate subgroups will be evaluated for the pairs of strips such that the rhythm classification of the 12-lead ECG is either SR or AF and such that the strip generated by the SUT is classified as either SR or AF and such that the strip generated by the SUT is classified as either SR or AF. The evaluation will be assessed with the concordance of classifications, i.e. the percentage P of identical classifications by the SUT and the reference method, into each of the four following subgroups :
SR with a HR between 50 and 99 bpm
SR with a HR between 100 and 150 bpm
AF with a HR between 50 and 99 bpm
AF with a HR between 100 and 150 bpm
Assessment of the clinical equivalence of ECG waveforms
Clinical equivalence of ECG waveforms will be qualitatively and quantitatively assessed between the 6-leads generated by the SUT and the leads I, II, III, aVR, aVL, aVF of the 12-lead ECG by a board of certified cardiologists : The visibility and polarity of the P waves, QRS complexes and T waves will be determined by cardiologists and according to a set of predetermined rules.
Assessment of the clinical equivalence of ECG waveforms
The durations of the QT intervals, QRS complex widths, and PR intervals will be measured by cardiologists with a caliper on the first beat of the 6 marked PQRST complexes and according to a set of predetermined rules for each of the 6 leads of the strips generated by the SUT and the leads I, II, III, aVR, aVL, aVF of the 12-lead ECG.
Determination of the heart rate
The heart rate will be determined by independent cardiologists, or cardiac technicians supervised by cardiologists, from each six-channel strip recorded with the SUT and from each lead I, II, III, aVR, aVL, aVF of the 12-lead strip of the reference ECG. For each simultaneous pair of strips, a reviewer will independently select a common lead with the best signal quality. Then, the reviewer will determine one or several window(s) on the selected lead according to a set of predetermined rules. Finally the number N of complete RR intervals inside these windows and the duration Dt (< 30s) of the windows will be measured with a caliper. The heart rate will then be calculated as 60*N/Dt. The reader-estimated heart rates will later be compared to the heart rates calculated by the SUT
