Just from my own research and after asking a couple of M.D.s about it I
found the following. (1) A current passed through the heart (arm to arm) causes a violent contracture of the heart muscle which along will stop the heart. (2) The same current interrupts the nerve impulses from the Vegas nerve (brain control to the heart), the sinus node and the atrioventricular node in the heart (it's pacemaker).

I seem to remember in Physics 101 I was was told that the heart will go into v-fib at about .300 amps that would be less then 1/3 of an amp! Well, it takes voltage to make current, right? I always think of the human body as a 10kOhm 2W resistor. But if the current is directed arm-to-arm across the chest (i.e. through the heart) even a small current can cause big trouble. A small shock applied at a particularly inauspicious time in the heart's electrical cycle can cause a deadly rhythm disturbance. 73, George T.
