Mobile headphones can interfere with heart devices

View Comments


As someone that is constantly concerned about the amount of radiation my BlackBerry emits, you might call me the paranoid sort. So when I heard about this recent report by the FDA saying that headphones — yes, even the kind all you multimedia-enabled BlackBerry users have — can interfere with heart devices like pacemakers if held too close, I had to write about it:

“Headphones contain magnets, and some of these magnets are powerful,” said the study’s leader, Dr. William Maisel, a cardiologist at Beth Israel Deaconess Medical Center in Boston and a heart device consultant to the federal Food and Drug Administration.

When headphones were about an inch from the device, interference was detected nearly one-fourth of the time — in four of the 27 pacemaker patients and 10 of the 33 with defibrillators. A pacemaker reset itself in one patient.

Dr. Maisel said that the headphones could have an effect even when unplugged. Don’t be too concerned, however: the report also said that as long as you keep the headphones away from your chest, you should be fine.
