Despite extensive vascular and cardiological evaluations, the etiology of approximately one third of ischemic strokes cannot be definitively identified, resulting in their classification as cryptogenic stroke (CS) [1, 2]. Atrial fibrillation (AF) is a major cause of ischemic stroke [3] and AF diagnosis in patients with CS is important to prompt oral anticoagulant (OAC) therapy initiation to prevent recurrence of events. However, since AF can be intermittent and asymptomatic, conventional short-term and sporadic electrocardiographic (ECG) monitoring strategies are frequently inconclusive [4, 5].
