There are two basic types of pacemakers.
- Single-chamber pacemakers stimulate one chamber of the heart, either an atrium or more often a ventricle.
- Dual-chamber pacemakers send electrical impulses to both the atrium and the ventricle and pace both chambers. A dual-chamber pacemaker synchronizes the rhythm of the atria and ventricles in a pattern that closely resembles the natural heartbeat.
Dual-chamber pacemakers are usually used to treat a slow heart rate.

What is the sa node?
The SA node is the "pacemaker" of the heart. Cells in the SA node are called "pacemaker" cells and they direct the contraction rate of the entire heart by generating action potentials.
