"...Electrical conduction is what doctors are looking at when they are staring at the heart monitor. Generally speaking, this impulse creates a squeeze that actually creates your pulse. There are times however, that this isn’t the case. A person could have a normal looking electrical conduction on the monitor and still have no pulse. "...When the [natural pacemaker] fails to create a beat, countless other cells within the heart attempt to create the beat instead. The result is numerous areas of the heart that “shock” it all at the same time, from different directions. Instead of a steady contracting beat, what you get is a heart that looks like it’s having a seizure. The effect is a heart that doesn’t pump blood through it... When you shock these cells with this large amount of electricity, it forces all of the electrolytes out of the cells at the same time. The hope, and it’s really just a hope, is that the heart’s normal operation... will take over again. "...In fact, after every shock ever given to someone in cardiac arrest, the rhythm created for a few seconds is asystole ["flatline"], with the heart rhythm temporarily stopped. It takes a few seconds for the normal pathways to get going again. If you had asystole *before* you shocked it, all you would do is burn the heart with the heat created from the shock. As every steak lover knows, don’t burn the meat! Medium-well please…"
