Low Yield of Mobile Cardiac Outpatient Telemetry after Cryptogenic Stroke in Patients with Extensive Cardiac Imaging.

Abstract

Detection of paroxysmal atrial fibrillation (AF) after cryptogenic stroke (CS) or transient ischemic attack ranges from 5% to 24%, but previous studies have had varying definitions of both. We aimed to evaluate the yield of up to 30 days of mobile cardiac outpatient telemetry (MCOT) for this dysrhythmia in CS patients who had undergone extensive cardiac imaging before monitoring.
