I would call the manufacturer of the pacemaker and talk to them. I wouldn't take any chances and pacemakers might vary depending on age and type.

we ran into the same issue with DH's pacemaker. The strong magnets can cause interference with the pacemaker. We ended up having to go a different route for our range.

The Induction Site linked below has a whole section devoted to all the research done on whether they will interfere with pacemakers. I, too, have a PM, but had no problems when i tested an induction cooktop in the store. I'm not actually buying one, but for entirely different reasons.

I found the article pretty enlightening, and reassuring that I would have experienced no issues. To be certain, call the PM company: they're always very helpful about matters like this.
