Implantable Cardioverter Defibrillator (ICD)
Implantable Cardioverter Defibrillator (ICD) An ICD is a surgically inserted electronic device that constantly monitors your heart rate and rhythm. When it detects a very fast, abnormal heart rhythm, it delivers electrical energy to the heart muscle. This causes the heart to beat in a normal rhythm again.
RELATED TERMS--------------------------------------
Heart The hollow, muscular organ responsible for pumping blood through the circulatory system.
Abnormal Not normal. Deviating from the usual structure, position, condition, or behavior. In referring to a growth, abnormal may mean that it is cancerous or premalignant (likely to become cancer).
Muscle Tissue made up of bundles of long, slender cells that contract when stimulated.
SIMILAR TERMS--------------------------------------
Implant (dentristy) Artificial device replacing tooth root; may anchor an artificial tooth, bridge, or denture.
Implantable Insulin Pump A small pump placed inside of the body that delivers insulin in response to commands from a hand-held device called a programmer.
Implantation The process by which an embryo becomes attached to the inside of the uterus (7-14 days in humans).
IMPLANTS Dental Implants are titanium inserts that are surgically placed into the jawbone by an oral surgeon or a periodontist, and then allowed to integrate into the bone. This process may take up to six months. The implants then can be restored with a post and an artificial tooth that is either screwed into the implant or cemented onto the implant. Implants are more costly than crowns, dentures or bridges and are appropriate only for patients who demonstrate good oral hygiene. Implants enable the dentist to provide the patient with artificial teeth that look and function much more like natural teeth and are as secure as natural teeth. Implants also may be attached to a denture to allow denture wearers a more secure and functional option. Patients must follow the proper home care instructions and visit the dentist at the recommended intervals or the implants can fail or fracture. There are no strict age limitations as to who can receive implants; in fact, implants have been placed on children, adults and the elderly.

INLAYS/ONLAYS Inlays and onlays are more permanent types of restorations similar in longevity to crowns. A more conservative tooth preparation is done which allows a tooth to maintain more of its original characteristics. A mold is made with a special plaster and from that model the inlay or onlay is custom made. Inlays and onlays can be fabricated from gold, porcelain or a composite resin. The inlay or onlay is then cemented or bonded into place to give the tooth superior support. An inlay differs from an onlay in that the onlay material covers one or more cusps of a tooth and generally is a better choice if the tooth has a fracture.
IHSS Idiopathic Hypertrophic Subaortic Stenosis is another term used synonymously with hypertrophic obstructive cardiomyopathy.
Iliac Veins The two principal veins returning blood from the lower part of the body. The iliac veins eventually join to form the inferior vena cava.
Immunosuppression The artificial suppression of the immune response, usually through drugs, so that the body will not reject a transplanted organ or tissue. Drugs commonly used to suppress the immune system after transplant include prednisone, azathioprine (Imuran), mycophenolate mofetil (CellCept), and cyclosporine (Neoral).
Implantable Cardioverter Defibrillator (ICD)
Infarction Tissue death due to lack of oxygen-rich blood.
Infectious Disease Team A team of physicians and nurses who help control the hospital environment to protect you against harmful sources of infection.
Informed Consent A process of reaching an agreement based on full disclosure. Informed consent has components of disclosure, comprehension, competence and voluntary response. Informed consent often refers to the process by which one decides to donate the organs of a loved one.
Innominate Veins The two principle veins returning blood from the upper part of the body. The innominate veins eventually join to form the superior vena cava.
Intensive Care Unit (ICU) A special nursing area devoted to providing continuous and immediate care to seriously ill patients.
