Assess Safety, Efficacy and Usability of Application for Atrial Fibrillation Vocal Marker

A Prospective, Open Label, Multi-Center, Pilot Study to Assess Safety, Efficacy and Usability of Application for Atrial Fibrillation Vocal Marker

Voice Assist Arrhythmia Monitoring (VAAM) is an application running on smartphones and/or landline phones that performs vocal tests for the monitoring of abnormalities in the heart rhythm.

Following ICF signature and process and eligibility confirmation, subject will have a training session to assure correct application use. The subjects will be asked to pronounce few vowels 3 times a day to be evaluated by the application analysis algorithm at the patient natural environment.

At the same time, a single lead ECG system will be recorded synchronously ECG for reference with the use of dedicated recording device
