Brief summary
The purpose of this study is to determine whether screening for atrial fibrillation by intermittent ECG recording and initiation of anticoagulation treatment among high risk individuals is cost-effective and can lower the incidence of stroke.
Interventions
ECG screening for atrial fibrillation with intermittent ECG recording (Zenicor device) for 14 days. Introduction of anticoagulants in the case of atrial fibrillation.
