A pacemaker is inserted through a minor surgical procedure where the cardiologist makes an incision and guides wires into the heart. Here's a more detailed explanation:
The Pacemaker Insertion Procedure:
-
Incision: The cardiologist makes a small incision, typically 5 to 6 cm (about 2 inches), just below the collarbone, usually on the left side of the chest.
-
Vein Access: The cardiologist then inserts the pacemaker wires, also called pacing leads, into a vein located near the incision site.
-
Lead Placement: Using X-ray guidance (fluoroscopy), the pacing leads are carefully guided through the vein and positioned in the appropriate chamber(s) of the heart. These leads deliver electrical impulses to regulate the heartbeat.
-
Generator Placement: A small pocket is created under the skin, near the incision, to house the pacemaker generator.
-
Lead Connection: The pacing leads are connected to the pacemaker generator.
-
Testing and Programming: The pacemaker is tested to ensure it's functioning correctly. The cardiologist then programs the pacemaker to deliver the appropriate electrical impulses based on the patient's individual needs.
-
Closure: The incision is closed with sutures, and a sterile dressing is applied.
The entire procedure typically takes a few hours. Patients usually stay in the hospital overnight for observation.
