About potential interference with medical devices
Most consumer electronic devices, including laptops, tablets, smartphones, wearables, and audio devices, contain magnets, components, and radios that emit electromagnetic fields that might interfere with medical devices. For example, implanted pacemakers and defibrillators might contain sensors that respond to magnets and radios when in close contact.
Most medical device manufacturers recommend keeping a source of potential interference a safe distance away from your medical device (at least 6 inches / 15 cm apart or at least 12 inches / 30 cm apart when using a wireless charger). Consult your physician and medical device manufacturer for specific guidelines. Manufacturers often provide recommendations on the safe use of their devices around wireless or magnetic products to prevent possible interference.
If you suspect that an Apple device is interfering with your medical device, stop using it and consult your physician and your medical device manufacturer.
