Abstract:
We present a structured approach for managing patients with cardiac implantable electronic devices in ambulatory surgery centers. Safe peri-operative management requires thorough assessment of patient, device, and procedural factors. Key priorities include determining pacemaker dependency, anticipating electromagnetic interference (EMI), and understanding device-specific magnet responses. Magnets generally induce asynchronous pacing in pacemakers and disable anti-tachycardia therapies in implantable cardioverter defibrillators (ICDs), but knowledge of device-specific functions is essential. Patients needing formal device reprogramming, such as pacemaker-dependent individuals with ICDs undergoing procedures above the umbilicus, are not suitable for ambulatory surgical centers. EMI mitigation, proper monitoring, and individualized planning are essential.
