The DEFINE AFib study is a prospective, observational, post-market clinical study. This nationwide, app-based study — sponsored by Medtronic — includes approximately 5,000 patients with a self-reported history of Aﬁb and either a Reveal LINQ™ or LINQ II™ insertable cardiac monitor (ICM).
We will use our research ﬁndings to improve the understanding of how data from the LINQ™ family of ICMs can be used to guide the management of Aﬁb patients.
The study uses a combination of device data, electronic health records, and Apple® Health app data to evaluate the association between complex patterns of Afib and clinical outcomes and quality of life.
DEFINE AFib is an app-based study designed to answer questions about patterns of atrial fibrillation and impact on healthcare utilization and quality of life. Watch the engaging session recording from HRS 2021 to learn more about DEFINE AFib and how the unique study design brings research to a new level.
Eligible patients must meet the following criteria:
Additional criteria may apply.
By referring patients to the study, you will help us gather the crucial data needed to help us improve patient care. This data could help uncover insights that better guide the management of Aﬁb and help you improve your patients' outcomes now and in the future. In addition, physicians are compensated for their time spent recruiting patients.
