Over 80 percent of
wireless phones are analog phones, which researchers
say do not pose a health risk. Some digital phones,
however, have been found to cause interference with
some pacemakers. Most pacemakers do not continually
send a pulse to the heart, therefore the radio
frequency interference does not necessarily mean a
threat to life. Pacemaker users are aware of the
potential for interference from certain electromagnetic
devices. This would be no different from the caution
pacemaker users exercise around equipment such as MRI
machines. The effect of cellular phones on pacemakers
is being studied. If you have questions about using a
cellular phone near a pacemaker, consult your doctor
and your user's manual. Keep in mind that the
interference is caused by digital phones.
