Doctors always advise people who have had a pacemaker or defibrillator to not carry smartphones near the chest and not in a shirt pocket, although the risk of smartphones jamming the implanted devices is low.
The German cardiologist Philipp Lacur said that a distance of 15 cm between the smartphone and the chest is reasonable, and will not represent any restriction for the user in his daily life, so that this distance is considered unnecessary in most cases.
In general, the German doctor advises that you should check the possible interference between the smartphone and the implanted device by the doctor himself, as long as possible.
Scientists have focused on this topic recently through an article in the Heart Rhythm magazine, a specialized scientific study to examine the extent of the interference of the new iPhone 12 smartphone with implanted devices.
And doctors in the United States placed the new Apple phone on the chest of a patient carrying a pacemaker, which caused the function of the implanted device to be immediately impeded, and they confirmed that iPhones may prevent life-saving measures, especially when they are placed in a shirt pocket.
MagSafe
For his part, German cardiologist Florian Blaschke said that the "MagSafe" magnetic ring installed in the new iPhone 12 consists of 18 individual magnets, and appears to be so strong that it causes the implantable defibrillation device to malfunction for the entire time that the smartphone is close to the heart.
Apple responded to the scientific journal's report, and advised iPhone 12 owners on its support page to keep their mobile devices with MagSafe accessories, protection covers and induction charging bases at a safe distance from the implanted devices, in order to avoid any potential interference.
The American company stressed the need to keep a distance of 15 cm or even a distance greater than 30 cm when the smartphone is charged wirelessly by one of the wireless charging units.
The two doctors, Blasheh and Lacour, in cooperation with other researchers, conducted a study in 2020 to investigate any possible interference of smartphones with pacemakers, depending on the iPhone 6. But, undoubtedly, he returned to confirm that no interference occurred like the new iPhone 12 because the iPhone 6 phone Does not include the "MagSife" magnetic ring.
The German doctor advises that each patient should separately check whether his smartphone affects the function of the implanted devices, when the smartphone is placed directly on the chest or in everyday situations when phone calls are made, and the smartphone is placed on the right or left ear.
