I'm saying the same as Lynne, my father~in~law just had one put in, he's feeling sooooo much better now, and can get out and about and is looking soooo much better...
So, I'm saying, it might be just the ticket your dad needs....
The only one thing I will tell you, is that once he gets it in, there's one or two things he shouldn't do is run a
weed~whacker...*or something with a spark plug that would be close to the proximity of himself/body/torso....*
the spark from the spark plug can make the pacemaker skip a beat... but as long as he knows it, ther'es no problem..
