iPod can distrupt cardiac pacemakers
May 11, 2007
An iPod can tigger monitoring malfunctions in cardiac pacemakers due to electromagnetic interference, reports a study presented by a 17-year-old school student to a group of heart specialists at a meeting of the Heart Rhythm Society in Denver, Colorado.
Jay Thaker, lead author of the study and a student at Okemos High School in Okemos, Michigan, found that an iPod positioned 5 cm (2 in) inches from the chest of a patient fitted with a pacemaker caused electrical interference in 50 percent of devices. Some pacemakers seem to be effected even at a distance of 40 cm (18 inches).
Thaker will next look at the effects of iPods on implanted cardioverter defibrillators (ICDs).
In a open letter posted Wednesday, Apple Inc. CEO Steve Jobs countered claims by green groups that the iPod and computer maker lagged in recycling and removing toxic chemicals from its products. He said the company is already an industry leader when it comes to the environment and that Apple will continue to reduce its impact on the planet.
