Pacemaker / ICD Generator Change

What is an Pacemaker / ICD Generator Change?

A Pacemaker or ICD Generator Change is a procedure performed to replace the internal battery of your existing cardiac device. The pulse generator is a small metal unit located beneath the skin in the upper chest. It contains the battery and electronic circuits that control your pacemaker or implantable cardioverter-defibrillator (ICD).

Over time, the battery gradually depletes. A generator change involves replacing the battery unit while keeping the existing leads (wires) in place, provided they are functioning normally. This procedure is performed by a Cardiologist in a Cardiac Catheterisation Laboratory.
