An abstract presented this weekend at the AHA meeting (abstract) found that 23% of pacer and defibrillator devices dysfunctioned when placed in close proximity (<2cm) to ipod headphones. Those headphones with higher magnetic strength were more likely to cause a problem (EM strength in the headphones tested varied from 0-20 gauss, listed by brand in the abstract). They found no device dysfunction with headphones >3cm away from the device. The authors recommend keeping ipod headphones at least 3cm away from these devices, which given this study, seems like a very reasonable suggestion.
