ipad use if you have an implanted heart device.

Researchers at Central Valley Arrhythmia, Stockton,CA found the iPad 2 may cause implanted
heart devices to malfunction when placed on users chests. They found the magnets in an iPad
may alter the settings if implantable cardioverter defibrillators and possibly deactivate them.
Do not fall asleep with an iPad resting on your chest. To avoid this problem hold the iPad at a normal
reading distance.   Presented at the Heart Rhythm Society's annual meeting in Denver, CO.
