Role of ambulatory holter electrocardiographic monitoring in detecting atrial fibrillation in patients with ischemic stroke

Background

Atrial fibrillation (AF) accounts for 20-30% of ischemic strokes and is often paroxysmal and clinically silent, which limits its diagnosis on standard electrocardiography. Ambulatory Holter electrocardiographic (ECG) monitoring is the most accessible screening tool after ischemic stroke. This study assessed the diagnostic yield of short-duration ambulatory Holter monitoring for AF detection after ischemic stroke and identified the factors associated with detection.
