Potential interference of small neodymium magnets with cardiac pacemakers and implantable cardioverter-defibrillators.


BACKGROUND Magnetic fields may interfere with the function of cardiac pacemakers and implantable cardioverter-defibrillators (ICDs). Neodymium-iron-boron (NdFeB) magnets, which are small in size but produce strong magnetic fields, have become widely available in recent years. Therefore, NdFeB magnets may be associated with an emerging risk of device… (More)
