A defibrillator procedure typically refers to the surgical implantation of an implantable cardioverter-defibrillator (ICD). This involves inserting a device under the skin to monitor heart rhythm and deliver an electrical shock if a life-threatening arrhythmia occurs.
Here's a breakdown of what the ICD implantation procedure entails:
-
Incision and Pocket Creation: The clinician will make a small incision, usually near the left shoulder, to create a pocket under the skin and chest muscle. This pocket will house the ICD generator.
-
Electrode Placement: A thin, insulated wire (electrode) is inserted into a vein and guided to the heart. This is typically done using fluoroscopy (a type of X-ray) to visualize the heart and ensure proper placement. The electrode senses the heart's electrical activity and delivers the electrical shock if needed.
-
ICD Generator Placement: The ICD generator is placed into the pocket created under the skin.
-
Testing: The ICD is tested to ensure it can effectively detect and correct arrhythmias. This may involve inducing an arrhythmia to confirm the ICD's ability to deliver a life-saving shock.
-
Closure: The incision is closed with sutures or staples.
Important Considerations:
- Procedure Time: The procedure typically takes a few hours.
- Anesthesia: The procedure is usually performed under local anesthesia with sedation, although general anesthesia may be used in some cases.
- Recovery: Recovery time varies, but most people can return to their normal activities within a few weeks.
- Risks: As with any surgical procedure, there are potential risks, including infection, bleeding, and complications related to the electrode placement.
