Cardiac pacemaker
This article is about the natural pacemaker in the heart. For the article about the medical device that simulates the function, see
artificial pacemaker.The contractions of the
heart are controlled by chemical impulses, which fire at a rate which controls the beat of the heart.The
cells that create these
rhythmical impulses are called pacemaker cells, and they directly control the
heart rate. Artificial devices also called
pacemakers can be used after damage to the body's intrinsic conduction system to produce these impulses synthetically.
