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

The research study, published in the Heart Rhythm Journal, describes an implantable cardioverter-defibrillator (ICD) from Medtronic. Such ICDs can be deactivated by external magnets due to the technology used. This is precisely what can take place when an iPhone 12 is oriented appropriately.
In itself, MagSafe is not damaging and can be an advantage in everyday life, for example for cordless charging. The circularly placed magnets in the iPhone mean patients who carry Medtronics medical device in their bodies must be cautious when handling the new Apple smartphone.
MagSafe in iPhone 12 disables implanted defibrillator
As the scientists write in the research study, they evaluated their assumptions just by holding an iPhone 12 over a clients chest location– where the ICD is housed. An image shows that the defibrillator is disabled when the iPhone neighbors.

In the study, the scientists advise that medical professionals and manufacturers signal their patients to such issues.

A recent medical study shows that the MagSafe built into the iPhone 12 can apparently shut down implanted defibrillators. All it requires to do this is to bring the mobile phone close to it.

In the study, the researchers recommend that doctors and makers notify their clients to such issues. Not just iPhone 12 but also other wearables could have comparable results on medical equipment. Its imaginable that other producers might also significantly rely on magnets in the future to make charging easier, for example.
Apple mentions interference with medical devices
Apple itself composes in a support document that “magnets and electromagnetic fields may hinder medical devices, such as defibrillators and pacemakers”. At the same time, nevertheless, they point out that with iPhone 12, in spite of containing more magnets, they do not expect “to position a greater danger of magnetic interference to medical devices than previous iPhone designs”.
Users should call their doctor or gadget manufacturer with any questions for more particular information on possible constraints, according to Apple. This consists of, for instance, keeping a specific distance.
As Medical Xpress writes in its protection of the research study, manufacturers must think about much better safeguarding their devices versus such interference in the future. Devices from companies like Medtronic “continue to butt heads with customer devices– and they will continue to lose,” the report states.
