I also have a medtronics PM, that is on the list....the last time I was at the cardio docs office, not a soul there knew anything about this fda warning until I handed to them....I actually had to force them to set up mine so it reports the battery use every 30 days....If I were to see a drop on battery life I think I would have to insist on changing this out. at their expense of course...good luck hope all works out for you.....
