Movable music players such as the iPod do not induce electronic blocking in implanted cardiac pacemakers, a new study claims. Government researchers accounted in the current issue of BioMedical Engineering OnLine that they measured the magnetic fields produced by four different iPod models a fourth-generation iPod; iPod with video; iPod shuffle; and iPod nano and measured the voltages delivered inside a pacemaker by the magnetic fields from the iPods.They found out the music devices would have no affect on people with cardiac pacemakers. “Based on the observations of our in-vitro study, we conclude that no blocking can happen in pacemakers exposed to the iPods we tested,” wrote U.S. Food and Drug Administration researcher Howard Bassen and his colleagues.

All over the past year, there have been a number of media covers about iPod interference on cardiac pacemakers. But those reports were based on a single incident where a person with a pacemaker experienced dizziness when using an iPod. During an examination, doctors conducted a test with an iPod and found it interfered with the patient’s pacemaker.

The reports was publicized in the journal Heart Rhythm and prompted discussions about the use of warning labels for portable music and video players, according to background information in a news release about this new study.
