Overview

May support prolonged monitoring in cryptogenic stroke; leaves open whether detected AF alters anticoagulation or outcomes.

Structured PICO

Does continuous electrocardiographic monitoring using an implantable loop recorder detect asymptomatic atrial fibrillation in patients with cryptogenic stroke?

P
Population
54 patients with ischemic cryptogenic stroke, at risk for atrial fibrillation but without any history of arrhythmia or palpitations, admitted to a single center in Turin.
I
Intervention
Implantable loop recorder (ILR) implantation for continuous electrocardiographic monitoring with monthly trans-telephonic data collection.
O
Outcome
Detection of atrial fibrillation episodes lasting more than 5 minutes.surrogate

Long-term heart rhythm monitoring with an implantable loop recorder detects silent atrial fibrillation in nearly half of patients with cryptogenic stroke and AF risk factors.
