If your heart is out of rhythm or is beating too fast or too slow, a pace maker will be
programmed to override your body when necessary. This will of course make you
feel a lot better because your heart will constantly work as it should.
I will never forget an old man who was in the bed next to me in hospital last year.
He could hardly walk, hardly talk and was always falling asleep. He was taken to a
different hospital in the morning and returned the following day. I was staggered at the
difference in him. He had better colour, was more energetic and unfortunately wouldn't
stop talking.
