is your moms pacemaker a sensing pacing one? (I know we have talked about this but my mind is a colander sometimes) IF it is not a sensing an pacing one? the strain on her leads would be negligible and probably will never ever be a issue for her.. I just lost my oldest lead in 2009 and I got it in 1979!
So, she really doesn't need to worry, but I do understand it is always there in the back of your mind ALWAYS! I have driven the docs nutz how many times I have called and done a teletrace cause it "felt" like it did when the pacer was on its last legs... shortness of breathe etc and it be nothing more than asthma or allergies, blood pressure etc.. silly stupid little things that sent me into a tail spin. its just always there right ready to jump to the front of your thoughts... you become very hypochondriac about it. (doesn't help that THAT label right there? already ran in the family!) uggghhh

no, she should be good.. I know it wont be that much comfort for her but I truly doubt she will ever have a problem. How long has she had this now? Not that long if I remember right?
(I have gone thru 7 change outs and each time it is hard when they first tell you its time.. for at least 30 min or so.. the panic is just hard to describe)
