Pacemakers are fitted when an abnormality in the electrical pathway of your heart upsets your heartbeat and causes it to beat irregularly. Artificial pacemakers treat some of these abnormal rhythms and help improve your quality of life.
An ICD (implantable cardioverter defibrillator) might be fitted to prevent arrhythmias from deaths from sudden cardiac arrest (SCA). If your doctor has suggested that you need an ICD you may have experienced or may be at risk of experiencing an abnormal, fast heart rhythm. An ICD constantly monitors your heart rhythm and can deliver various electrical impulses to correct potential problems. It is made up of a small pulse generator, contains a battery and electronic circuits, and sophisticated leads that connect the generator to the heart. And ICD, like a pacemaker, is usually placed under the skin below your collarbone.
An S-ICD (subcutaneous implantable cardioverter defibrillator) is a more recent invention. S-ICD's are able to defibrillate the heart with only a lead that is placed just beneath the skin instead of into the heart. They are not suibable for all patients.
