Heart Rhythm: Pacemakers control the rate of the heart's beat. Defibrillators deliver shock(s) to try to return the heart to a normal rhythm.

Electricity!: Pacemakers and defibrillators have a generator and leads or wires. Pacers help patients predominantly with bradycardia or slow heart beats and defibrillators shock the heart when a life threatening rhythm disorder is detected. Very intelligent and amazing machines!
