FDA says RFID's interfere with pacemakers, defibrillators

The U.S. Food and Drug Administration, in collaboration with major implantable pacemaker and ICD manufacturers, demonstrated the effects of emissions from radio frequency identification (RFID) readers on common implantable cardiac devices. According to research published in the January edition of the HeartRhythm Journal, the official journal of the Heart Rhythm Society, the observed effects may cause increasing complications as RFID use expands in the medical device field. Read full text of study » The study, which looked at the electromagnetic interference susceptibility of 15 pacemakers and 15 ICDs caused by exposure to 13 RFID readers, concluded that low frequency RFID readers may pose the greatest risk to pacemakers and ICDs. While modern pacemakers and ICDs use filters to minimize susceptibility to higher-frequency signals, there is limited filtering of low frequency signals due to the design constraints of both pacemakers and ICDs.
