The US Food and Drug Administration warns that powerful magnets in some mobile phones and smartwatches can interfere with pacemakers and other embedded medical devices.
Studies have shown that these high-strength magnets can cause some implants to switch to “magnet mode” and stop functioning normally until the magnets move away from the device.
Many implants have a “magnet mode” that allows them to be safely operated during the following medical procedures: MRI Scan Doctors usually activate these functions by placing high-strength magnets near the implant. Removing the magnetic field restores normal operation of the medical device.
The FDA said patients with implanted medical devices should take the following precautions:
- Keep your cell phone or smartwatch 6 inches away, especially from embedded medical devices. heart Defibrillator. Do not carry these devices in the pockets above the medical implants.
- If you have a home monitoring system, use it to verify your device. Talk to your doctor if you have any symptoms or have questions about magnets in home appliances or implantable medical devices.
- When near high-strength magnets, devices in magnetic safe mode may stop working or change the way they work. For example heart Defibrillator You may not be able to detect a rapid heart rate known as tachycardia.Or it may switch pacemaker Moves to asynchronous mode and blocks its sensing function.
Embedded devices are designed to assist Cardiac dysfunction, Fast or slow heart rate, etc. The FDA warned in a government news release that patients could become dizzy, unconscious, or even die if the device failed.
The FDA has conducted its own tests on several products that use the high magnetic field strength magnet function and said it considers the risk to patients to be low. The agency said it was not aware of any adverse events associated with this issue at this time.
