Apple’s warning to keep iPhone 12 away from heart devices due to electromagnetic interference was further emphasized by US cardiologists this week in a new report (via NBC25 news).
Apple’s iPhone 12 series includes a range of magnets that help adjust the phone on Apple’s MagSafe charging accessories to maximize charging, and Apple already advises users with implanted pacemakers and defibrillators to keep iPhone and MagSafe accessories safe from them. devices.
To test the extent of the risk, Henry Ford Heart and Vascular Institute cardiologist Gurjit Singh and his colleagues recently conducted additional tests to see how much of an impact Apple products have.
According to Dr. Singh, more than 300,000 people in the United States undergo surgery to implant one of these devices each year, and around one in four smartphones sold last year was an iPhone 12. The heart devices have switches that respond to an external magnet to change the way the device works, allowing them to be controlled without the need for surgery.
Curious about the potential disruption of electrical devices, Dr. Singh and colleagues took an iPhone 12 Pro and passed it over the chest of a patient with an implantable defibrillator.
“When we brought the iPhone near the patient’s chest, the defibrillator was deactivated,” said Dr. Singh. “We saw on the external defibrillator programmer that the functions of the device were suspended and remained suspended. When we took the phone from the patient’s chest, the defibrillator immediately returned to its normal function.”
“We were all amazed,” he said. “We had assumed that the magnet would be too weak in a telephone to trigger the defibrillator’s magnetic switch.”
The findings are important, as Dr. Singh is an expert on the use of devices such as implantable defibrillators that detect irregular heartbeats and shock the heart back to a normal rhythm, and pacemakers that use power to keep the heart beating. Following the discovery, Dr. Singh and his colleagues immediately sent a report on their findings Heart rate medical journal published January 4, 2021.
“We believe that our findings have major consequences on a large scale for people who live daily with these devices, who without thinking will place the phone in the shirt pocket or upper pocket or coat – without knowing that it can cause the defibrillator or pacemaker to work on a way that can be potentially fatal. “
The comments underscore medical evidence published in January that warned that iPhone 12P models and related MagSafe devices could “potentially inhibit a patient’s life-saving treatment” due to magnetic interference with implanted medical devices.
