Validation Study of an Advanced Blood Pressure Monitor

Not Applicable

Completed

• Conditions: Atrial Fibrillation; Hypertension; Valvular Heart Disease

• Registration Number: NCT04030494
• Lead Sponsor: Withings

Brief Summary

The proposed clinical study aims to validate the effectiveness of the WPM04 blood pressure monitor developed by Withings as a diagnostic tool for cardiovascular disorders.

The detection of cardiovascular disorders is oriented along three axes, namely the measurement of blood pressure, the identification of rhythm disorders such as atrial fibrillation and the identification of heart murmur indicating valvular heart disease.
