What is a Pacemaker?
- A pacemaker consists of a battery, a computerized generator, and wires with sensors called electrodes on one end.
- The electrodes detect your heart's electrical activity and send data through the wires to the computer in the generator.
- It is placed in the chest or abdomen to help control abnormal heart rhythms. This device uses low-energy electrical pulses to prompt the heart to beat at a normal rate.
- If your heart rhythm is abnormal, the computer will direct the generator to send electrical pulses to your heart. The pulses then travel through the wires to reach your heart.
Implantable cardioverter defibrillators (ICDs)
ICDs are similar to pacemakers. However, besides using low-energy electrical pulses to control abnormal heart rhythms, ICDs also can use high-energy electrical pulses to treat certain dangerous arrhythmias.
Pacemakers are used to treat arrhythmias. Arrhythmias are problems with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm.

Cardiac resynchronization therapy is a proven treatment for selected heart failure patients that improves symptoms and extends survival.
