k What about wireless phone interference with
medical equipment?
Radiofrequency 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 in 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.
FDA continues to monitor the use of wireless phones for
possible interactions with other medical devices. Should harmful
interference be found to occur, FDA will conduct testing to assess
the interference and work to resolve the problem.
