While cell phone technology is rapidly evolving, the Food and Drug Administration (FDA) has devised a test method to measure the interference on cardiac pacemakers from cell phones. This standard will now enable pacemaker manufacturers to ensure that their devices are safe from cell phone interference.
MP3 Players and MP3 Player Headphones
Much like with cell phones, the NIH advises against placing an MP3 player (that is on) in your shirt pocket closest to your pacemaker, and suggests that if you strap the device to your arm while listening to music, you should strap it to the arm farthest from where your pacemaker was implanted.
Headphones may also pose a risk, because they typically contain a magnetic substance that, according to studies, may be linked to interference with pacemakers. To avoid this, the AHA advises that you should keep headphones at least 1.2 inches away from your pacemaker at all times, and never place them in your breast pocket or drape them over your chest. Do not allow a person who is wearing headphones to rest his or her head on your chest.
Anti-Theft Systems
Anti-theft systems are used at the entrances and exits of a wide variety of businesses, ranging from clothing stores to supermarkets, from libraries to some schools. These systems may cause minor interference with your pacemaker, although, in most patients, the interference is minimal. The FDA notes that, in the past 10 years, they have only received 44 reports of serious interactions between a pacemaker and an anti-theft system.
Experts still advise that you should be aware that these systems may be hidden or camouflaged in the entrances of businesses, and be mindful of lingering in areas where you see or suspect there may be an anti-theft system installed. If you see a device, keep your distance, and don’t lean on it.
