Study shows iPhone 12’s MagSafe might cause trouble for heart-patients

The study, released in the Heart Rhythm Journal, refers to an implantable cardioverter-defibrillator (ICD) from Medtronic. Such ICDs can be shut off by external magnets due to the technology used. This is precisely what can occur when an iPhone 12 is oriented appropriately.
In the study, the researchers recommend that doctors and makers alert their clients to such issues.

A current medical study reveals that the MagSafe constructed into the iPhone 12 can obviously deactivate implanted defibrillators. All it requires to do this is to bring the mobile phone near to it.

The research study, published in the Heart Rhythm Journal, refers to an implantable cardioverter-defibrillator (ICD) from Medtronic. Such ICDs can be shut off by external magnets due to the technology used. When an iPhone 12 is oriented appropriately, this is precisely what can happen.
In itself, MagSafe is not harmful and can be a benefit in everyday life, for example for wireless charging. Nevertheless, the circularly put magnets in the iPhone mean clients who carry Medtronics medical device in their bodies must take care when handling the brand-new Apple mobile phone.
MagSafe in iPhone 12 disables implanted defibrillator
As the scientists write in the research study, they tested their assumptions just by holding an iPhone 12 over a patients chest area– where the ICD is housed. When the iPhone is close by, an image shows that the defibrillator is disabled.

In the study, the researchers recommend that producers and doctors inform their patients to such problems. Not only iPhone 12 however also other wearables might have similar results on medical devices. Its imaginable that other producers could also increasingly turn to magnets in the future to make charging much easier, for instance.
Apple points out interference with medical devices
Apple itself composes in an assistance document that “magnets and electro-magnetic fields might disrupt medical devices, such as defibrillators and pacemakers”. At the exact same time, however, they discuss that with iPhone 12, regardless of consisting of more magnets, they do not anticipate “to present a greater threat of magnetic disturbance to medical gadgets than previous iPhone designs”.
Users should contact their doctor or gadget maker with any questions for more specific details on possible limitations, according to Apple. This consists of, for example, maintaining a specific distance.
As Medical Xpress composes in its coverage of the research study, manufacturers should consider much better protecting their devices against such interference in the future. Equipment from companies like Medtronic “continue to butt heads with customer gadgets– and they will continue to lose,” the report states.
