Because they're usually inductively coupled rather than RF coupled they shouldn't cause a problem I would think. They also have to detect a resonant coil near the primary before they'll output significant current because otherwise they'll heat up and burn out the primary coil. So while I wouldn't put the pace maker on top of one, I would think it wouldn't cause problems directly.
