@PG67 - Your husband should have received a card right after the pacemaker was implanted. Please check for a phone number. Call it. The manufacturer can answer your question. Or check with your doctor. I have an implanted device and have found that the manufacturer is more knowledgeable on this topic than the doctor. But you definitely need an official opinion from either source. For what it’s worth, my implant is a spinal cord stimulator. It is in my lower neck. My manufacturer approved a Fitbit on the wrist as long as I keep it away from my neck. But it could be different for a pacemaker.
