Study Overview
Brief Summary
The proposed clinical study aims to validate the diagnostic performance, compared to a reference ECG, of the electrocardiographic function of the BPM Core developed by Withings for the automatic identification of atrial fibrillation (AF).
Detailed Description
BPM Core is a blood-pressure monitor with an build-in single-channel electrocardiogram similar to a lead I.
Primary objective:
The primary objective is to demonstrate that Withings BPM Core has acceptable sensitivity and specificity in the automatic identification of AF and SR in comparison with a gold-standard diagnosis from a 12-lead ECG by board certified cardiologists.
The algorithm classifies the device signals into four categories: normal sinus rhythm (RSN), AF, arrhythmia other than AF, or non-interpretable. The latter category includes signals of insufficient quality to be interpreted with confidence.
This classification will be compared to the diagnosis made by three independent, blinded cardiologists based on a 12-lead ECG. The final diagnosis retained will be decided by majority with adjudication by a consensus of 3 to 6 cardiologists. The sensitivity and specificity of the device will then be estimated.
