NCT02714907

Brief Summary

The purpose of this study is to validate the quality of the ECG-signal acquired with the Cortrium C3 monitor. The intention is to evaluate whether the diagnosis of atrial fibrillation based on the ECG signal from the C3 monitor concurs with the current monitoring methods used in clinical practice.
