There is a lot more to electrocution but this is a start. For one, different forms of electricity may or may not induce ventricular fibrillation in the heart, which is where you drop and hope someone starts CPR as another runs for an Automatic External Defibrillator or AED. BTW, defibrillation is usually 200-360 joules or watt seconds of dc countershock.

If you survive, you may still go into renal failure 3-5 days later as the myoglobin in your blood clogs your kidneys. Ever noticed that brown jelly-like stuff when you fry a bloody steak? That's what your myoglobin looks like in your bloodstream after an electrical shock.
