Key result
Electromagnetic interference from medical devices and procedures such as LVADs and electrocautery can cause cardiac implantable electronic device malfunctions, though the overall risk appears low.
Why the study?
As CIEDs become more prevalent, acknowledging potential EMI from medical devices and procedures is critical, but large multicenter studies are lacking and current guidelines rely primarily on expert opinion and anecdotal experience.
Does electromagnetic interference from other medical devices and procedures affect the function of cardiac implantable electronic devices?
Does electromagnetic interference from other medical devices and procedures affect the function of cardiac implantable electronic devices?
Electromagnetic interference from various medical devices and procedures can disrupt CIED function, but current management relies largely on expert opinion due to a lack of robust multicenter data.
As cardiac implantable electronic devices (CIED) become more prevalent, it is important to acknowledge potential electromagnetic interference (EMI) from other sources, such as internal and external electronic devices and procedures and its effect on these devices. EMI from other sources can potentially inhibit pacing and trigger shocks in permanent pacemakers (PPM) and implantable cardioverter defibrillators (ICD), respectively. This review analyzes potential EMI amongst CIED and left ventricular assist device, deep brain stimulators, spinal cord stimulators, transcutaneous electrical nerve stimulators, and throughout an array of procedures, such as endoscopy, bronchoscopy, and procedures involving electrocautery. Although there is evidence to support EMI from internal and external devices and during procedures, there is a lack of large multicenter studies, and, as a result, current management guidelines are based primarily on expert opinion and anecdotal experience. We aim to provide a general overview of PPM/ICD function, review documented EMI effect on these devices, and acknowledge current management of CIED interference.

Barmore et al. (2022) conducted a review in Patients with cardiac implantable electronic devices (CIED). Electromagnetic interference from medical devices and procedures was evaluated. Electromagnetic interference from medical devices and procedures such as LVADs and electrocautery can cause cardiac implantable electronic device malfunctions, though the overall risk appears low.
