As a kid my mentor gave me an example. she told me that there were two stages of being that can be depicted on the heart monitor.
One is the wave that represent life and it shows that the heart is beating. Other is the straight line that shows that the heart has stopped beating. The one that is wavy and represents life is because heart is learning and the other is uniform and dead because the heart gas stopped learning.
What an analysis. Love the way you started out with this. You are right. Well done. Thanks a lot.
