The prevailing U.S. standard for the RF immunity of medical devices is the 2007 revision of the Association for the Advancement of Medical Instrumentation (AAMI) Standard 60601-1-2, which mirrors the International Electrotechnical Commission (IEC) Standard 601-1-2. Formally recognizing this standard, the Food and Drug Administration (FDA) says that it “will allow manufacturers to ensure that cardiac pacemakers and defibrillators are safe from cell phone EMI [electromagnetic interference].”
Medtronics, one of the principal manufacturers of pacemakers, provided this RF immunity information in 2009 for its devices, and other manufacturers should have incorporated similar resilience into their own products:
“Medtronic pacemakers/defibrillators are designed to operate normally in electric fields measuring 100 volts per meter” (V/m) and “to operate normally within RF levels that meet the government Maximum Permissible Exposure (MPE) limits” for electric fields at “150 kHz and up,” including “[s]ources such as: radio transmitter antennas, television transmitter antennas, cellular telephone antennas, RF welding equipment, dielectric heaters, radar.”
