Where are pacemakers typically placed?

Pacemakers are typically placed underneath the left clavicle, specifically in a subcutaneous pocket just below the skin. This location is chosen for several reasons. Firstly, the left clavicle area provides adequate tissue for the pacemaker and its leads to be securely positioned, while also being close to the heart, which is necessary for effective lead placement. The leads are usually inserted through a vein and threaded into the heart chambers where they can monitor and manage the heart's electrical activity.

This placement also allows for easier access during follow-ups or necessary adjustments, as well as minimizing potential complications associated with deeper placements. Furthermore, positioning it beneath the left clavicle is often more aesthetically acceptable for patients. Other placements, such as those mentioned in the alternatives (the right arm, abdomen, or right leg), are not standard and could lead to complications or suboptimal functionality of the device.
