Pacemakers and iPods Revisited

Finally, another study confirms the safety of iPods and pacemakers.
For this study, Bassen tested a second-generation iPod Nano, a second-generation iPod shuffle, a fifth-generation iPod Video with a 30-gigabyte hard drive, and a standard iPod with a 15-gigabyte hard drive and dock connector.


For all of them, data taken at 0.5 and 1.0 cm from the case showed a field of 0.2 micro-Tesla or less, with a highly localized 100 kilohertz sinusoidal signal.


The fields existed only in an area of about 1 cm2 and were not measurable at distances greater then 1 cm from the case, Bassen said.


He also found no measurable fields near the earphone cable, except at the earphone itself.
Hopefully, the American Heart Association will pick up on this story and print a retraction to their earlier fear-mongering quiz.

I wonder how long before a company comes out with their first MRI safe Pacemaker. I heard medtronics or medrad are doing clinical trials. Great post.
