Pace Maker

I just would like to know i have my grandmother that just went into
the hospital for the lower heart was not beating right. They are
going to put in a pace maker. They compared it to a short in a car
that goes bad and the pace maker will jump start the heart when i
needs it .. Well here we go MY Question is what causes the heart to
become week. Is it lack of exercise or diet. Please let me know the
answer. I have stuided health with all of the alteritive speacialast
out there.

Thanks
