Inflammation and the risk of atrial high-rate episodes (AHREs) in patients with cardiac implantable electronic devices.

Introduction: Atrial high-rate episodes (AHREs) are associated with an increased risk of developing atrial fibrillation and thromboembolism. The characteristics of 'real world' patients developing AHREs are poorly known.

Methods: We included 496 consecutive patients with cardiac implantable electronic devices (CIEDs).
