A defibrillator brings the cells of the heart back into a unified and timed contraction by introducing a electrical charge ( measured in joules which are equivalent to a one-amp-second of amplitude).

Simply speaking, a defibrillator works by using a moderately high voltage (something like 200–1000 volts) to pass an electric current through the heart so it's shocked into working normally again. The important thing is getting the current to flow through the heart, so where the paddles are applied is crucial.
