WHAT IS AN ICD, OR IMPLANTABLE CARDIOVERTER DEFIBRILLATOR?
An ICD is a minicomputer that is implanted under the skin of the upper chest area and is small enough to fit in the palm of your hand. It monitors your heart for fast and potentially dangerous heart rates and delivers therapy in the form of a shock, delivered directly to your heart when it senses a dangerously fast heart rhythm. While helping your heart maintain its rhythm, the ICD also stores information that your doctor can use to program the ICD for the best possible therapy.
HOW AN ICD WORKS
Once implanted, the device detects your heart rhythm through one or more thin, flexible insulated wires called leads, which are placed on or inside the heart muscle and attached to the device. The leads transmit your heart rate information to the ICD. When an abnormal heart rhythm occurs, the ICD sends an electric shock to the heart muscle to defibrillate it—or to stop the cycle of rapid beats.
ICDs can provide lower-or higher-energy therapy to treat rhythm disorders, depending on the need. Sometimes the therapy is uncomfortable and sometimes it is not. Whether you can feel it or not, your ICD is doing its work to respond to a dangerous rhythm disorder.
THE ABBOTT COMMITMENT TO SAFE, RELIABLE AND EFFECTIVE ICDS
Since the first implantable pacemaker was developed in 1958, millions have benefited from pacemaker therapy. The remarkable story of the first cardiac pacemaker is embedded in Abbott’s history – Abbott continues its commitment to revolutionizing arrhythmia management with our implantable cardiac defibrillators (ICDs). The Fortify Assura™ ICD and Ellipse™ ICD are two examples.
