Question: 1 / 400

When utilizing a temporary pacemaker, where is the lead typically placed?

Left atrium

Right ventricle

The lead of a temporary pacemaker is typically placed in the right ventricle. This positioning is critical for effective pacing because the right ventricle is directly involved in pumping blood to the pulmonary artery, where it can then go to the lungs for oxygenation. Placing the lead in the right ventricle allows for the electrical impulses generated by the pacemaker to stimulate the heart muscle effectively, promoting coordinated contractions and maintaining a sufficient heart rate.

In contrast, leads placed in locations such as the left atrium, left ventricle, or coronary sinus do not provide the same level of efficacy in pacing, particularly for addressing issues related to ventricular function or heart rate management. The utilization of the right ventricle for lead placement ensures that the pacemaker can adequately support the heart's pumping action, especially in situations of bradycardia or other types of heart block, where reliable pacing is necessary to ensure adequate cardiac output.
