find a cardiologist What Is an Implantable Cardiac Defibrillator?An Implantable Cardiac Defibrillator (also known as ICD) is a small electronic device that sends an electric shock to the heart to stop abnormal, fast heart rhythms. The ICD is used to treat life- threatening heart rhythms that lead to sudden death. The device is inserted under the skin in the chest or abdomen. The procedure is similar to that of a pacemaker insertion. One wire is connected to the heart and another is connected to the defibrillator unit. The defibrillator unit monitors the heart rhythm, sends an electrical shock and keeps a record of the events. If the heart is beating normally, the ICD is inactive. When an abnormal, fast heart rate, known as a "tachycardia", is detected, the ICD will send electric shock signals to the heart. The electric shock converts the abnormal rhythm to a normal rhythm. The low energy electric shocks delivered by the ICD do not harm the patient or anyone in physical contact with the patient. The patient may feel the symptoms of the tachycardia as it begins. Call 911 immediately if any of the following occur:
After the ICD is inserted, the physician will advise the patient about limiting activities for a time while the incision heals. Most patients resume normal activities after recovering from the procedure. Every patient is given an ICD identification card to be carried with the patient at all times. The card provides information about the ICD and instructions in case of emergency. It is safe for the patient with an ICD to be around most household electrical appliances. Other sources that can interfere with the ICD are MRI scans, digital cellular phones, metal detectors at airport security gates, heavy-duty electrical power equipment, arc welders, a running car engine (do not lean over the engine), and certain electrical power surgical tools. A health care provider discusses these and other precautions with the patient.For more information, speak with your health care provider. If your health care provider would like to refer you to a cardiologist, ask for a referral to a Saint Vincent Heart Center cardiac specialist. Information is also available by contacting your local chapter of the American Heart Association or call the national office at (800) 242-8721 or visit their website at www.americanheart.org.
