Gianna Chien, a 14 year student from Stockton, California, is presenting a study to over 8,000 doctors at the Heart Rhythm Society that finds the iPad can interfere with implanted defibrillators.
If a person falls asleep with the iPad2 on the chest, the magnets in the cover can “accidentally turn off” the heart device, said Chien, a high school freshman in Stockton, California, whose father is a doctor. “I definitely think people should be aware. That’s why I’m presenting the study.”
Chien notes that iPad 2 uses 30 magnets to the hold a smart cover in place. The magnets aren’t a problem when the device is held out in front of a user; however, if rested on the chest it can cause problems.
The iPad triggered ‘magnet mode’ in 30% of the 26 volunteers tested with defibrillators. It did not interfere with four pacemakers or a loop-recorder. Walter Chien, a cardiac electrophysiologist, helped his daughter test patients.
Apple declined to comment put did refer to the device’s online produce guide which says patients with pacemakers should keep the iPad at least six inches away.
