enEnglish
arrhythmia definition: any variation from the normal rhythm or rate of the heart beat.
Arrhythmias, Cardiac definition: Any disturbances of the normal rhythmic beating of the heart or MYOCARDIAL CONTRACTION. Cardiac arrhythmias can be classified by the abnormalities in HEART RATE, disorders of electrical impulse generation, or impulse conduction.
Arrhythmia definition: Any variation from the normal rate or rhythm (which may include the origin of the impulse and/or its subsequent propagation) in the heart.
Cardiopulmonary Bypass definition: Diversion of the flow of blood from the entrance of the right atrium directly to the aorta (or femoral artery) via an oxygenator thus bypassing both the heart and lungs.
heart/lung bypass definition: diversion of the blood flow to the heart directly to the aorta, via a pump oxygenator, avoiding the heart and/or the lungs; a form of extracorporeal circulation used in heart surgery; see BLOOD OXYGENATOR for the portion that oxygenates the blood and EXTRACORPOREAL CIRCULATION for the portion that recirculates one's blood.
Coronary Artery Bypass definition: Surgical therapy of ischemic coronary artery disease achieved by grafting a section of saphenous vein, internal mammary artery, or other substitute between the aorta and the obstructed coronary artery distal to the obstructive lesion.
coronary bypass definition: surgical procedure creating a bridge between the ascending aorta and one or more of the three major coronary arteries, distal to an obstructive lesion, using autologous tissue transplanted from the saphenous vein.
Coronary Artery Bypass Surgery definition: Surgery performed to bypass partially or completely occluded coronary arteries, thereby increasing the blood supply of the heart.
Crisscross Heart definition: A developmental malformation of the heart characterized by a twisted but not defective atrioventicular connection. The abnormal rotation of the ventricular mass around its long axis results in the crossing of the inflow streams of the two ventricles. Other features include hypoplasia of the TRICUSPID VALVE and RIGHT VENTRICLE.
Fetal Heart definition: The heart of the fetus of any viviparous animal. It refers to the heart in the postembryonic period and is differentiated from the embryonic heart (HEART/embryology) only on the basis of time.
Heart definition: The hollow, muscular organ that maintains the circulation of the blood.

Heart definition: Organ with cavitated organ parts, which is continuous with the systemic and \npulmonary arterial and venous trees. Examples: There is only one heart.
HEART definition: A hollow muscular organ which receives the blood from the veins and propels it into the arteries. It is divided by a musculomembranous septum into two halves -- right or venous and left or arterial -- each of which consists of a receiving chamber (atrium) and an ejecting chamber (ventricle). (NCI)
Heart definition: A hollow organ located slightly to the left of the middle portion of the chest. It is composed of muscle and it is divided by a septum into two sides: the right side which receives de-oxygenated blood from the body and the left side which sends newly oxygenated blood to the body. Each side is composed of two chambers: the atrium (receiving blood) and ventricle (ejecting blood).
Heart Aneurysm definition: A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
heart aneurysm definition: aneurysmal dilatation of a portion of the wall of the ventricle, usually the left, or, rarely, a saccular protrusion through it (false aneurysm of the heart); usually consequent to myocardial infarction but other causes such as bacterial endocarditis or trauma have been described.

Heart Atria definition: The chambers of the heart, to which the BLOOD returns from the circulation.
Atrial definition: Of or relating to a cavity or chamber in the body, especially one of the upper chambers of the heart.
Cardiac Atrium definition: The paired upper chambers of the heart. The left atrium receives oxygenated blood from the pulmonary vein and pumps blood into the left ventricle. The right atrium receives venous deoxygenated blood from the entire body via the superior and inferior vena cavae and pumps blood into the right ventricle.
Heart Auscultation definition: Act of listening for sounds within the heart.
Heart Block definition: Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.
heart block definition: impairment of conduction in heart excitation; often applied specifically to atrioventricular heart block.
Heart Block definition: An impairment of transmission of the cardiac electrical impulse along the fibers normally responsible impulse propagation.
Heart Catheterization definition: Procedure which includes placement of catheter, recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, etc. Specific angiographic injection techniques are also involved.
heart catheterization definition: procedure which includes insertion of a tubular device into the heart for recording of intracardiac and intravascular pressure, obtaining blood samples for chemical analysis, and cardiac output measurement, injecting or withdrawing fluids, etc.
Cardiac Catheterization definition: A procedure in which a thin plastic tube (catheter) is inserted into an artery or vein in the arm or leg and then advanced into the chambers of the heart or into the coronary arteries. Catheterization can measure blood pressure within the heart and how much oxygen is in the blood. It's also used to get information about the pumping ability of the heart muscle. Catheters are also used to inject dye into the coronary arteries. Catheters with a balloon on the tip are used in the procedure called percutaneous transluminal coronary angioplasty.
Heart Defects, Congenital definition: Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.
Heart Diseases definition: Pathological conditions involving the HEART including its structural and functional abnormalities.

heart prosthesis definition: pumping mechanism that duplicates the output, rate, and blood pressure of the natural heart; may replace the function of the entire heart or a portion of it, and may be an intracorporeal, extracorporeal, or paracorporeal heart.
Prostheses, Heart definition: Prostheses designed for total replacement of the biological natural heart. These devices typically consist of an implantable mechanism that includes one or more pumps, valves, cannulae, and a power source. Heart prostheses are used to provide blood circulation to patients with a debilitated or completely failed heart. Some devices are designed for implantation of the pumping mechanism with a physical connection to an external power source (e.g., electrical, pneumatic), and others are totally implantable but may need a wireless, transcutaneous transmission of power from an external source. Percutaneously powered prostheses are mostly intended for temporary use before a heart transplant is possible; transcutaneously powered heart prostheses are intended for permanent use.
