Identifying Atrial Fibrillation Events Following Cryptogenic Stroke

Identifying Atrial Fibrillation Events Following Cryptogenic Stroke

In 20–40% of ischaemic strokes, a definitive cause is not identified, despite extensive evaluation1; this condition has been defined as ‘cryptogenic stroke.’ Atrial fibrillation (AF) is a well-known cause of ischaemic stroke and about 15% of strokes are attributable to a documented AF. Many strategies have been explored to improve detection of AF, ranging from in-hospital monitoring, serial electrocardiography and Holter monitoring and the use of external events (or loop recorders) or insertable cardiac monitors (ICM).
