pacemaker

pacemaker
n.
1) a device used to produce and maintain a normal heart rate in patients who have heart block. The unit consists of a battery that stimulates the heart through an insulated electrode wire (lead) attached to the surface of the ventricle (epicardial pacemaker) or lying in contact with the lining of the heart (endocardial pacemaker). A pacemaker may be used as a temporary measure with an external battery or it may be permanent, when the whole apparatus is surgically implanted under the skin. Modern pacemakers sense when the natural heart rate falls below a predetermined value and then stimulate the heart (demand pacemaker).
2) the part of the heart that regulates the rate at which it beats: the sinoatrial node.
