Overview

It is known that atrial fibrillation after stroke significantly increases the risk of stroke or systemic embolism. Accordingly, efforts have been made to detect hidden atrial fibrillation and apply treatment using anticoagulants instead of antiplatelet agents. The conventional method used to screen for atrial fibrillation in stroke patients who did not have atrial fibrillation at first admission is 24-hour Holter monitoring. This study will compare the detection rate of atrial fibrillation with discontinuous ECG monitoring three times a day and 72 hours of single-lead ECG patch monitoring compared with the conventional Holter test.
