In this method, a small incision is made near your collarbone and the leads are maneuvered through a vein into the heart. The tip of each lead is positioned next to the inside wall of the heart the endocardium. Thoracotomy: In this approach, your chest is opened and thin oval patches made of rubber and wire mesh are sewn onto the outside of the heart epicardium.
These patches are connected to the leads. Sternotomy: This approach is similar to a thoracotomy in that the chest is opened. The difference is that the incision is made over the breastbone the sternum and the leads are advanced into the heart. A sternotomy may be combined with coronary artery bypass surgery or heart valve surgery. Subxiphoid approach: This approach is also similar to a thoracotomy, but the incision is made slightly to the left of the breastbone sternum.
What can you expect? Before the operation Usually, the procedure is scheduled ahead of time. Before the procedure starts, inform your doctor if you: Have ever had a reaction to any contrast dye, iodine, or any serious allergic reaction for example, from a bee sting or from eating shellfish Have asthma Are allergic to any medication Have any bleeding problems or are taking blood-thinning medication Have a history of kidney problems or diabetes Have body piercings on your chest or abdomen Have had any recent change in your health Are, or may be, pregnant.
During the operation Usually, implantation is performed when you are awake but sedated with your chest area numbed with local anesthetics similar to the anesthetics dentists use. Your surgeon will perform tests to find the best location for the leads and to ensure that the leads are connected correctly to the ICD. Once the ICD is implanted, additional testing may be performed to ensure the system will effectively correct your arrhythmia problem.
After the operation After the procedure, you will be taken to a recovery room. You will probably feel drowsy and may feel some soreness around the site where the ICD was implanted. You can take pain medication to manage your discomfort. Depending upon your condition and which procedure you had, you may stay in the hospital for a few days. Before you leave, the ICD system may be tested again.
But, it is best to ask your doctor what types of machines or equipment you should avoid. Also ask what you can and cannot do when you have an ICD. Read about living with an ICD. If you have an Implantable Cardioverter Defibrillator, be aware of your surroundings and the devices that may interfere with its operation. Potentially disruptive devices include those with strong magnetic fields.

Our online community of survivors and caregivers is here to keep you going no matter the obstacles. The American Heart Association recommends that before a patient is considered to be a candidate for an ICD, the arrhythmia in question must be life threatening and doctors have ruled out correctable causes of the arrhythmia, such as: Acute myocardial infarction heart attack Myocardial ischemia inadequate blood flow to the heart muscle Electrolyte imbalance and drug toxicity Because many people do not understand their underlying condition — such as heart failure or genetic predisposition for risk of sudden cardiac arrest — and because ICDs are used primarily to prevent sudden cardiac death, they in turn may not understand the benefits versus the limitations of having an ICD implanted.
Why do I need an ICD? Your doctor may recommend an ICD if you or your child is at risk of a life-threatening ventricular arrhythmia because of having: Had a ventricular arrhythmia Had a heart attack Survived a sudden cardiac arrest Long QT syndrome Brugada syndrome A congenital heart disease or other underlying conditions for sudden cardiac arrest How is an ICD implanted?
How does an ICD work? Depending on how much electrical shock it delivers, a defibrillator's battery can last anywhere from three to eight years. When the battery's voltage runs low, a new ICD will be implanted. However, the defibrillator's leads most likely will not be replaced. Defibrillator therapy is part of a larger treatment program that may include medications, proper nutrition, moderate physical activity and healthy lifestyle choices.
Breadcrumb Home Medical services Heart and vascular care Your cardiovascular health Defibrillator implant surgery Defibrillator implant surgery. The device can be set to restore normal heart rhythm in several ways: Anti-tachycardia pacing ATP , or "overdrive pacing," is a sequence of electrical impulses delivered to the heart when it beats dangerously fast tachycardia. Cardioversion is a low-energy shock delivered at the same time as a heart beat after a sequence of ATP impulses fails to restore normal heart rate.
Bradycardia pacing is needed when the heart beats too slowly bradycardia. Electrical impulses will speed the heart rate. Defibrillation will stop a severely abnormal heart rhythm by delivering a high-energy shock.
Defibrillator implant surgery Defibrillators usually are implanted through small incisions in the skin, near the collarbone. After defibrillator implantation Following surgery, you need to visit the electrophysiologist for routine follow-up visits. During each visit, the defibrillator will be checked by a programmer device that will indicate: Whether the defibrillator is working properly.
