Atrial Fibrillation

Detecting biomarkers of early Atrial Transformation in AF

Study Scope and Protocol

This large scale 3,000 patient AF study spans up to 10 years, and is designed to detect biomarkers of early atrial transformation in atrial fibrillation. Participants are required to apply a wearable ECG monitor for one week durations every month or quarter, in ambulatory and home settings.

During the study, the Vivalink Biometrics Data Platform and continuous ECG monitor were used for remote patient monitoring to capture the ECG rhythm, integrated into a mobile patient app, and then transmitted it to the cloud. Data from the cloud was then sent to an arrhythmia detection algorithm for retrospective analysis and reporting.

"The capabilities of the Vivalink ECG sensor will enable us to capture a larger continuous dataset to identify imaging, serum and digital biomarkers of AF risk and progression in the study."
