phone interference
with medical equip-
ment?
Radio Frequency (RF)
energy from wireless
phones can interact
with some electronic
devices. For this reason,
the FDA helped develop
a detailed test method
to measure Electro
Magnetic Interference
(EMI) of implanted
cardiac pacemakers
and defi brillators from
wireless telephones. This
test method is now part
of a standard sponsored
by the Association for
the Advancement of
Medical Instrumentation
(AAMI). The fi nal draft,
a joint effort by the
FDA, medical device
manufacturers, and
many other groups, was
completed in late 2000.
