As the owner of a four-year-old pacemaker, I have often found myself trying to explain what they are, what they mean to other people. Just a warning here — a pacemaker will keep a heart beating. It is not a substitute for needing a replacement valve or a bypass or many of the other things done to keep a heart working properly. These are all procedures that might well b done in conjunction with getting a pacemaker.
Newer pacemakers are not metal and allow their owners to get MRIs and pass through airport checkpoints. Mine is metal, so not me.
Pacemaker batteries last for 10 to 12 years. How come no other battery lasts that long?
