The Single Chamber Pacemaker VVIR is designed to monitor the heart's electrical activity and deliver electrical impulses to regulate the heartbeat when necessary. It is indicated for patients with bradycardia who require pacing support to maintain adequate heart rate and cardiac output.

The implantation of a Single Chamber Pacemaker VVIR involves several key steps, beginning with the placement of the pacemaker generator under the skin near the collarbone. A lead, which contains electrodes, is then inserted through a vein into the heart's right ventricle. The lead is secured in place, and its position is confirmed using fluoroscopy or other imaging techniques. Once the lead is positioned correctly, it is connected to the pacemaker generator, and the incision is closed.
