Conditions

Atrial Fibrillation

Brief summary

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.

Detailed description

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

Interventions

DEVICEVoice Assist Arrhythmia Monitoring (VAAM)

application flag the potential occurrence of irregular heart rhythms suggestive of atrial fibrillation (AF) and notify to further investigate the occurrence of the suspected AF episode by prompting user to initiate ECG test to confirm.
