Trial Summary

What is the purpose of this trial?

DEFINE AFib is a prospective, observational, post-market clinical study administered to patients via the Medtronic Discovery app platform. This study will enroll approximately 5,000 patients in the United States who have a Reveal LINQ or LINQ II ICM (or future market-released LINQ devices) and an Apple® iPhone® with iOS version 13 or higher. Interested participants will be screened through the Medtronic Discovery app and those eligible will complete an app-based informed consent. Participants will receive health-focused and quality of life surveys at variable timepoints. DEFINE AFib will measure healthcare interactions using administered surveys to identify said interactions. The Medtronic Discovery app will provide participants with a summary of their ICM data. Participants will be followed up to 5 years or to the end of their ICM service life.
