I also reluctantly got PM for A/V node dis function / aFib. Heart pauses disappeared immediately and I feel much better. I had them adjust settings to allow heart rate to go a little faster for treadmill workout. So if you like to exercise, mention settings. No trouble w iPhone or iPad.. just remind myself to not carry them within 6-8” of PM. Going through airport security , I go through body scanner.. no problem. My PM doesn’t stop my aFib episodes.. I take Sotalol/ Diltiazem since Sept. and haven’t had any episodes. Oh, I do feel PM, it makes that area achy sometimes. Good luck Monday!
