Understanding Your Procedure
A pacemaker or implantable cardioverter-defibrillator (ICD) is a small electronic device that helps regulate and monitor your heart’s rhythm. The device is placed just beneath the skin near your collarbone and connected to your heart using thin wires (leads). The pacemaker sends gentle electrical impulses when your heart beats too slowly. An ICD monitors your heart rhythm and delivers a shock if it detects a dangerously fast rhythm, helping protect you from sudden cardiac arrest.
What to Expect During a Pacemaker Procedure
- The procedure is typically performed in a specialized cardiac lab under local anesthesia and sedation, so you’ll be comfortable but awake.
- Thin leads are inserted through a vein (usually in your upper chest) and guided to your heart, then connected to the device which is placed just beneath your skin.
- Most patients stay in the hospital overnight so the care team can monitor the device function and your recovery.
- After discharge, you’ll receive detailed instructions about caring for the incision, avoiding certain arm movements for a few weeks, and what signs to watch for.
- Ongoing follow-up visits (and often remote monitoring) will ensure your device is working properly and your rhythm remains stable.
