A Study to Determine if Identification of Undiagnosed Atrial Fibrillation in People at Least 70 Years of Age Reduces the Risk of Stroke


About this study

The purpose of this study is to determine if an AF detection intervention in men and women at least 70 years of age with undiagnosed atrial fibrillation (AF) or atrial flutter (AFL) reduces the person-years incidence rate of stroke compared to usual care (no AF detection intervention).
