The short answer is it shocks the heart into a working rhythm.

To shock the heart back into a viable rhythm. Fibrillation is literally an abnormal rhythm-so de-makes it normal.
AHA (American Heart Association) estimates a 70% increase in survival where early fibrillation is administered.
AHA copy and paste:
Defibrillation
Defibrillation is a process in which an electronic device gives an electric shock to the heart. This helps reestablish normal contraction rhythms in a heart having dangerous arrhythmia or in cardiac arrest. In recent years small portable defibrillators have become available. These are called automated external defibrillators or AEDs.

Fibrillation is basically the erratic quivering of your heart rather than its normal pumping beat. An electric shock across the heart will paralyze the heart muscles, causing it to stop altogether. Ideally, the body's natural pace maker will then take over and the heart will start beating normally again. It's kind of like hitting the RESET button on your computer.

When the heart is fibrillating, it is basically quivering. Defibrillating shocks it back into a normal rhythm.

Wikipedia:
It uses an electrical shock to reset the electrical state of the heart so that it may beat to a rhythm controlled by its own natural pacemaker cells.

To provide an electrical shock to stop a person's heart from fibrillation.
