Effect of Pacemaker Insertion on Arrhythmias (Heart Rhythm Disturbances)
An artificial pacemaker may work as a substitute for the heart's natural pacemaker, the sinoatrial (SA) node. Artificial pacemakers help treat some arrhythmias by generating regular impulses that make...

Reasons for Procedure
A pacemaker can be inserted when:
- The body's natural pacemaker, the sinoatrial (SA) node, is not working properly. When the SA node is not working correctly, the heart can beat too slowly.
- There are malfunctions in the atrioventricular (AV) node, the part of the heart’s electrical system that sends signals from the SA node to the ventricles. This leads to a very slow heartbeat.
- Heart performance in people with severe symptoms of congestive heart failure and a weakened heart muscle ( cardiomyopathy ) needs to be improved. This is called biventricular pacing, or cardiac resynchronization therapy.
- Cardiac surgery is being done.
