Why the study?
Current smartphones incorporate more magnets for wireless charging and accessories, potentially causing CIEDs to inadvertently revert into magnet mode.
Do modern smartphones and accessories cause magnetic interference in patients with cardiac implantable electronic devices?
Do modern smartphones and accessories cause magnetic interference in patients with cardiac implantable electronic devices?
Modern smartphones and accessories containing strong magnets can trigger magnet mode in CIEDs when in close contact, reinforcing the FDA recommendation to maintain a 6-inch distance between these devices and CIEDs.
May warrant advising CIED patients on smartphone proximity; leaves open prospective risk quantification.
PURPOSE OF REVIEW: The risk of cardiac implantable electronic device (CIED) interference from cell phones was previously thought to be low based on older studies. Current generation of smartphones have incorporated more magnets for optimization of wireless charging, attachment of accessories, and convenience functionalities. These magnets have the potential to cause CIEDs to inadvertently revert into magnet mode. The purpose of this review is to summarize recent findings on smartphones and their accessories causing interference on CIEDs. RECENT FINDINGS: Recent reports have demonstrated that the iPhone 12 series and accessories have the capability to cause CIED magnetic interference. Current generation of smartphones, smartwatches, wireless headphones, and accessories have the potential to cause CIEDs to revert into magnet mode in both in vivo and ex vivo experiments. The risk of a clinically significant event is unlikely as long as the Food and Drug Administration (FDA) recommendations are followed; keeping smartphones and accessories at least six inches away from CIEDs.
