In brief: Pacemakers
A pacemaker is a battery driven device.
It is actually a small computer. Some of its functions are like a radio receiver, its pacing function is just delivering a tiny shock to the heart. A defibrillator delivers a bigger shock to the heart.

In brief: Electrical energy
Electrical energy is stored in within the pacemaker "can" or "generator".
At regular intervals, the electrical energy is released through pacemaker leads and reaches the heart. This electrical energy, when applied to the muscle the heart, causes the heart contract.
