Single chamber refers to pulse transmitter, battery and implanted cardiac electrode. Dual chamber means that two electrodes are implanted in the heart, one in the atrium and the other in the ventricle. The single chamber is mainly implanted in the ventricle, and there is no electrode implanted in the atrium. In addition, there are three-chamber pacemakers and multi-chamber pacemakers, which are mainly aimed at patients with bradycardia and heart failure and need to be implanted with three-chamber pacemakers. Among all kinds of pacemakers, single-chamber pacemakers have the lowest price.
According to the specific hospital, the specific medical level and the specific policies of the local government, the price can be used as a reference. Three-chamber pacemakers are mainly used for patients with heart failure and decreased ejection fraction. Implanting a three-chamber pacemaker may be the most expensive kind of pacemaker.
