Apple has expanded the number of its products that should be kept "a safe distance" from cardiac devices because of the potential for electromagnetic interference.

A support document now lists a wide range of products, including AirPods, Apple Watches, HomePods, iPads, Beats, Mac computers, iPhone 12 models, and MagSafe accessories. These specific products contain magnets that, "under certain conditions, magnets and electromagnetic fields might interfere with medical devices. For example, implanted pacemakers and defibrillators might contain sensors that respond to magnets and radios when in close contact."

A study reported earlier this month, that the iPhone 12 Pro Max with MagSafe technology, designed to optimize wireless charging, interfered with cardiac implantable electronic devices when tested in vivo and ex vivo, with differences observed in susceptibility between cardiac devices.

Following other published reports of potential electromagnetic interference, the US Food and Drug Administration issued an advisory in May, stating that "cell phones do not seem to pose a significant health problem for pacemaker wearers," but that patients should avoid carrying a phone directly over an implantable device.

A new support document, also advises customers to keep their "Apple product a safe distance away from your medical device (more than 6 inches/15 cm apart or more than 12 inches/ 30 cm apart if wirelessly charging)."

If you suspect that your Apple product is interfering with your medical device, stop using your Apple product and consult your physician and your medical-device manufacturer.
