Evaluation of an Ultraportable ECG Recording Device and Its Visualization Software for the Detection of Atrial Fibrillation

The purpose is to demonstrate the usefulness of WitCard and WitDisplayer in the diagnosis of AF but more generally in the qualification of the heart rhythm and the diagnosis of cardiac arrhythmias. The main objective is therefore to demonstrate that at least 90 +/- 0.03% of ECGWs are interpretable by a physician and the primary endpoint will therefore be the ratio of the number of ECGWs that allowed a physician to make a diagnosis. rhythmic (ECGW interpretable) and the total number of ECGW recorded and viewed. The clinical trial as part of the CE medical device certification process for secondary objectives and ancillary studies will be required to assess the diagnostic performance of the WitCard + WitDisplayer system, the quality of the ECGW recorded by the WitCard, the the safety of using the WitCard, the technical performance of the WitCard ECG recorder, the ergonomics of the WitCard, and finally the performance of automatic cardiac rhythm classification algorithms.

a software to visualize, measure, annotate, comment, archive, and share the different ECGs acquired with the WitCard (ECGW) of different patients.

the ratio between the number of ECGWs that allowed a physician to make a rhythmic diagnosis (ECGW interpretable) and the total number of ECGWs recorded and visualized.
