There are many types of pacemakers, the most common being single-chamber and dual-chamber pacemakers. Single-chamber and dual-chamber pacemakers are used in patients with bradycardia who do not have severe heart failure.
Single-chamber refers to one pulse transmitter, one battery, and one implanted cardiac electrode. Dual-chamber means that two electrodes are implanted in the heart, one in the atrium and one in the ventricle, and single-chamber is implanted mainly in the ventricle, with no electrodes implanted in the atrium. There are also tri-chamber and multi-chamber pacemakers, which are implanted mainly in patients with bradycardia combined with heart failure. Among the various types of pacemakers, single-chamber pacemakers are the least expensive,
Depending on the specific hospital, the specific level of medical care, and the specific policies of the local government, the price can be used as a reference. Triple-chamber pacemakers are mainly used in patients with heart failure combined with decreased ejection fraction, and implantation of a triple-chamber pacemaker may be among the most expensive of pacemakers.
