Detecting Atrial Fibrillation in the Emergency Department in Patients with Cardiac Implantable Electronic Devices.

Background: Clinical guidelines emphasize identifying atrial fibrillation (AF) as a strategy to reduce stroke risk. Cardiac implantable electronic device (CIED) interrogation at the point of care may facilitate AF detection, increasing opportunities to identify patients at high risk for stroke.

Objectives: This study sought to quantify AF prevalence and assess stroke risk in patients with a CIED who presented to the emergency department (ED).
