FYI :
I have been informed by my doc.that there was no need to worry about
pacemakers and microwave ovens. Actually, he showed me a JAMA article that
reported tests on all brands of pacemakers presently manufactured in the
U.S. the article came to the conclusion that pacemakers are NOT sensitive
to the amounts of RF.leaked by microwave ovens
Didn't say anything about the older models of pacemakers though.
