Murder by magnet

Here's an article that the script writers for CSI or House could use inspiration for a story next season:

Researchers found that while common magnets for home and office use with low magnetic strength posed little risk, stronger magnets made from neodymium-iron-boron (NdFeB) may cause interference with cardiac devices and pose potential hazards to patients. NdFeB magnets are increasingly being used in homes and office products, toys, jewelry and even clothing....

Two spherical magnets of eight and 10 millimeters in diameter and one necklace made of 45 spherical magnets were tested on 70 patients, 41 with pacemakers and 29 with ICDs. Magnetic interference was observed in all patients. The cardiac devices resumed normal function after the magnets were removed.

I like to think that it must be a very fun job being a researcher for (say) House, as I assume they spend most of their time reading weird case studies in the medical journals that can be varied a little to form the basis of the difficult diagnosis of each episode. Of course, being a doctor might help too.
