Pacemaker with automatic activation of a magnetic resonance imaging mode: A single-center experience

Introduction: In patients with permanent pacemakers, magnetic resonance imaging (MRI) traditionally requires resource-intensive manual device reprogramming before and after the scan putting demands on clinical resources. Methods: In this single-center case series, we report five MRI procedures in three patients with a pacemaker using an always-on MRI workflow facilitating feature (MRI Guard 24/7) that automatically detects MRI conditions and adjusts the pacing mode without the need for pre- or post-scan checks. Results: All scans were completed successfully, with automatic switching into MRI mode and reverting to the permanent setting. No device reconfigurations were required pre- or post-scan. Discussion: We discuss the potential of this feature to streamline MRI workflows, reduce staffing demands and improve access to timely imaging for patients with cardiac implantable electronic devices.
