A 17-year-old high school student has done a study which proves iPods can cause cardiac implantable pacemakers to malfunction. The study, presented at a meeting of heart specialists in the US, says the iPod causes harm just by interfering with the electromagnetic equipment monitoring the heart. The study tested the effect of iPods on 100 patients who had pacemakers implanted.
Electrical interference was detected half of the time when the iPod was held just 2 inches from the patient8217;s chest for 5 to 10 seconds. Interfering with the telemetry equipment caused the device to misread the heart8217;s pacing and in one case caused the pacemaker to stop functioning altogether.
The study was held at the Thoracic and Cardiovascular Institute at Michigan State University. The results were presented at the Heart Rhythm Society annual meeting in Denver.
Jay Thaker, lead author of the study and a student at Okemos High School in Okemos, Michigan, concluded that iPod interference can lead physicians to misdiagnose actual heart function. Thaker, whose father is an electrophysiologist and whose mother is a rheumatologist, said he asked his dad about a potential interaction between pacemakers and iPods.
8220;We looked online but didn8217;t see anything. Then, one of his patients asked him if there would be a problem, so my father put me in touch with Dr Krit Jongnarangsin,8221; Thaker said. Jongnarangsin, a long-time friend of Thaker8217;s father, is the senior author of the study and an assistant professor in the Division of Cardiovascular Medicine at the University of Michigan.
