What about wireless phone interference 
with medical equipment?
Radio frequency energy (RF) from wireless 
phones can interact with some electronic 
devices. For this reason, FDA helped develop a 
detailed test method to measure 
electromagnetic interference (EMI) of 
implanted cardiac pacemakers and 
defibrillators from wireless telephones. This test 
method is now part of a standard sponsored by 
the Association for the Advancement of Medical 
instrumentation (AAMI). The final draft, a 
joint effort by FDA, medical device 
manufacturers, and many other groups, was 
completed on late 2000. This standard will 
allow manufacturers to ensure that cardiac 
pacemakers and defibrillators are safe from 
wireless phone EMI.
FDA has tested hearing aids for interference 
from handheld wireless phones and helped 
develop a voluntary standard sponsored by the 
Institute of Electrical and Electronic Engineers 
(IEEE). This standard specifies test methods 
and performance requirements for hearing aids 
and wireless phones so that no interference 
occurs when a person uses a “compatible” 
phone and a “compatible” hearing aid at the 
same time. This standard was approved by the 
IEEE in 2000.
