Modern Cardiac Implantable Electronic Devices (CIEDs) allow continuous monitoring of cardiac electrical activity through one or more electrodes. Atrial High Rate Episodes (AHRE) are defined as device detected, asymptomatic, atrial tachy-arrhythmias, which are found in approximately 20–30% of CIED patients after 1 year of average follow-up.1,2 AHRE are associated with an increased risk of thromboembolic (TE) events and clinically overt Atrial Fibrillation (AF) (standard 12-lead ECG recording or a single-lead ECG tracing of ≥ 30 s showing irregular heart rhythm with no P waves), moreover their prevalence is expected to increase with population aging and comorbidities, representing a significant future management challenge.
