The replacement of a pacemaker battery involves which of the following actions?

The replacement of a pacemaker battery primarily involves the removal of the old pulse generator. In pacemaker systems, the pulse generator, which includes the battery, is housed in a small device implanted under the skin. When the battery runs low or needs replacement, the entire pulse generator—rather than just the battery itself—is typically removed from the body. This procedure ensures that the new battery and any associated electronic components are functioning correctly as a cohesive unit.

While it may seem intuitive to think one could just change the battery, pacemakers are sealed units, and the design does not permit for the battery to be replaced independently of the entire generator. Therefore, during this procedure, the old pulse generator will be extracted safely, and a new one will be implanted.

Reprogramming the pacemaker settings and installing a temporary pacemaker may be required at times, but the fundamental action being addressed in this context is specifically the removal of the outdated pulse generator. This ensures the longevity and efficacy of the patient's cardiac pacing management.
