A pacemaker box change is a straightforward procedure to replace the pulse generator (the device “box”) when the battery reaches the end of its lifespan. The existing leads are usually left in place if they are functioning properly.
Pacemaker batteries typically last between 6 and 15 years depending on usage. Replacement is required before the battery is fully depleted to ensure continuous heart rhythm support.
Under local anaesthetic, a small incision is made over the existing pacemaker site. The old device is removed and replaced with a new generator, which is then connected to the existing leads.
This is usually a shorter procedure than the original implant, with most patients returning home the same day or after a short stay.
