iPad can interfere with heart devices

The iPad 2 can be bad for your heart — with a study showing is some cases the tablets interfere with lifesaving heart devices because of the magnets inside.

The research was carried out by 14-year-old Gianna Chien, who presented her findings to 8,000 doctors at the Heart Rhythm Society meeting in the US.

The research offers a valuable warning for people with implanted defibrillators, which deliver an electric shock to restart a stopped heart, said John Day, head of heart-rhythm services at Intermountain Medical Center in Murray, Utah, and chairman of the panel that reviews scientific papers to be presented at the Denver meeting.
