Removal of permanent pacemaker pulse generator with replacement of pacemaker pulse generator; dual lead system

AI EXPLANATION: A pacemaker pulse generator is the small, battery-powered device implanted under the skin that monitors and regulates the heartbeat. In a dual-lead system, two thin insulated wires connect the generator to two chambers of the heart. When the generator's built-in battery nears the end of its operational life, an outpatient surgical procedure is performed to replace it. A surgeon makes an incision over the existing device, disconnects the old generator from the leads, tests the leads to confirm they are functioning properly, connects a new generator to the existing wires, and closes the incision.
