I'm told that another rhythm is The Bee Gees, 'Stayin Alive'. A nephew of mine is an ambulance technician and (when this was first reported on Saturday I was with him) I asked how many folks they could rescue from a major cardiac event. "1 in 10" is apparently a good rule of thumb. Some events are small but too much time elapses, some are so big that even having it IN a hospital will not save the person.
The movies and TV drama's a have a lot to answer for in the expectations of what can be done.
