Accuracy of Cardiac Acoustic Biomarkers Recorded by the Wearable Cardioverter Defibrillator

Accuracy of Cardiac Acoustic Biomarkers Recorded by the Wearable Cardioverter Defibrillator

Evaluate data accuracy of cardiac acoustic biomarkers (CABs) recorded by the Wearable Cardioverter Defibrillator (WCD) as compared to the AUDICOR AM acoustic cardiography recorder.

Single arm, prospective, non significant risk device study to evaluate data accuracy of cardiac acoustic biomarkers (CABs) recorded by the Wearable Cardioverter Defibrillator (WCD) compared with the CABs data simultaneously recorded by an acoustic cardiography recorder, the AUDICOR AM device.
