Bill is correct on this. The reason I know a little about it is because my Grandpa and a friend had one. The thing is about Pacemakers, there's no way for them to be shielded by themselves (no path to ground). This was some years back so they may or may not have changed. Back then, microwave ovens had just gotten popular, and the price dropped, so everyone was buying them. That was a big concern at that time. I did repair work for North American Phillips on TV sets (Philco, Sylvania, and Magnavox), and we got a flier about this if we worked on any microwave ovens. About that time is when the microwave sniffer probes became a hot item to check the cabinets for leakage. A strong electrical field, or any RF field that is strong enough, could cause the pacemaker to fire pre-maturely or not fire when needed. There supposed to have been advances in them but for what I do not know. I would start by contacting her doctor about this and get the info for the manufacturer. The doctor may have the information there, or will tell you who to contact. My biggest concern rather than the equipment is the antenna, and the proximity to it. If I'm not mistaken, there was something about pacemakers and high tension power lines too. This would be a similar item, just a different frequency. It's way better to be safe than sorry.

If I may respectfully suggest, something this important should not be
left to the members of this group, no matter how well intentioned they
may be.  You should contact the manufacturer of the pacemaker and get
the information from them.  They will probably tell you "no RF at
all", because they want to cover themselves, but you should press for
copies of their test results.  Don't take no for an answer.

And good for you for being concerned.
