| Summery : Portable media players such as iPods are unlikely to interfere with heart pacemakers, a U.S. Food and Drug Administration researcher reported on Thursday.
His tests of a variety of iPods showed they did not produce enough of an electromagnetic field to interfere with the devices. FDA researcher Howard Bassen and colleagues set up a complex experiment using a saline-filled bag to simulate the human body and a coil sensor designed to pick up electromagnetic emissions. |

They measured the magnetic fields produced by four different iPod models: a fourth-generation iPod and an iPod with video, and an iPod nano and an iPod shuffle. They also measured the voltages delivered to the inside of the pacemaker by the magnetic fields from the iPods.
All their measurements indicated the iPods could not affect cardiac pacemakers, they reported in the journal BioMedical Engineering OnLine.
"We measured magnetic field emissions with a 3-coil sensor
placed within 1 cm (half an inch) of the surface of the player. Highly localized fields were observed (only existing in a one square cm area)," they wrote.
