- A pacemaker placement is the implantation of a small electronic device that will be placed in the chest (underneath the collarbone) to help manage electrical heart problems.
- It is important to keep the heartbeat from slowing to a dangerously low level.
- A pacemaker is composed of three parts:
- a pulse generator
- one or more leads
- an electrode on each lead.
- When the heartbeat is too slow or irregular, a pacemaker stimulates the heart to beat.
Types of pacemaker
- A single-chamber pacemaker delivers electrical impulses to your heart's right ventricle.
- To help control the timing of contractions between the two chambers, a dual-chamber pacemaker delivers electrical impulses to the right ventricle and right atrium of your heart.
- For persons with heart failure and abnormal electrical systems, a biventricular pacemaker, commonly known as cardiac resynchronization therapy, is used. This stimulates the lower chambers of the heart (the right and left ventricles) to make the heartbeat more efficiently.
