Teen discovers iPad 2 interferes with functioning of pacemaker
Washington: A teenager from California has found that the magnets in iPad 2 tablets and covers are capable of interfering with cardiac rhythm devices, like pacemakers, Heart Rhythm Society has said.
The research conducted by 14-year-old Gianna Chien of Stockton, who initially organized the study as part of a school science fair project, discovered that cardiac rhythm devices can be affected by magnets and radiofrequency energy in products ranging from cellphones to MRI machines.
When heart devices are near magnets, they switch into "magnet mode" that can potentially disrupt function, Fox News reported.
With help from her cardiologist dad, she asked 26 patients with implantable cardiac devices (ICDs) to hold the iPad 2 at reading distance, at this length the iPad caused no electromagnetic interference.
However, when the patients placed the tablet on their chests, as if they had gone to sleep with the iPad there, "magnet mode" was triggered in 30 percent of patients` ICDs.
