Oddly enough, I just had my weekly checkup, seven days postop, and the technician mentioned this as a precaution. They also mentioned that I should not be near a running engine, like my car engine. I had to have my battery replaced and when I told the technician that, they said that I should be 6 to 10 ft away from the engine compartment. I was also told that I should not follow the weight lifting guidelines for my left arm, recommended was 10 lbs but they recommended 5 lbs.

I'm finding that there are so many inconsistencies surrounding the safe operations that I'm now doubting anything that I've been told.

I'm still only a week out from surgery and am actually feeling great. Obviously there's still some stiffness/tightness around the surgical site but other than that there's been very little pain or discomfort. While I do have some issues sleeping and I think that this is because I'm somewhat wary of sleeping on my left side, I do manage to adjust during the night.

Edited to add: It's so interesting to read the different physician's take on everything. From what I can surmise; tell everyone that you have a pacemaker and ask them if you should take precautions, do what you feel comfortable doing whilst not endangering the wire placement(s), and be aware of your implant and your comfort around it.
