Term

Definition
| severe pain and constriction about the heart,usually radiating to the left shoulder and down the left arm, creating a feeling of pressure in the anterior chest. |
|
|
Term
cardiac tamponade
TAM-poh-nod |
|
Definition
| compression of the heart caused by the accumulation of blood or other fluid within the pericardial sac.the accumulation of fluid prevents the ventricles from adequately filling or pumping blood. life-threatening if untreated. |
|
|
Term
|
Definition
| disease of the heart muscle itself, primarily affecting the pumping ability of the heart. results in elargement of the heart (cardiomegaly) and dysfunction of the ventricles of the heart. |
|
|
Term
|
Definition
| condition characterized by weakness, breathlessness,abdominal discomfort. Edema in the lower portions of the body resulting from the flow of the blood through the vessels being slowed and outflow of blood from the left side of heart is reduced. pumpimg ability is progressively impaired to the point that it no longer meets bodily needs; also known as cardiac failure. |
|
|
Term
|
Definition
| the narrowing of the coronary arteries to the extent that adequate blood supply to the myocardium is prevented. |
|
|
Term
|
Definition
| inflammation of the membrane lining of the valves and chambers of the heart caused by direct invasion of bacteria or other organisms and leading to deformity of the valve cusps. abnormal growths called vegetations are formed on or within the membrane. |
|
|
Term
| hypertensive heart disease |
|
Definition
| a result of long-term hypertension. the heart is affected because it must work against increased resistance due to increased pressure in the arteries. |
|
|
Term
|
Definition
| is drooping of one or both cusps of the mitral valve back into the left atrium during ventricular systole,resulting in incomplete closure of the valve mitral insufficiency. |
|
|
Term
|
Definition
| heart attack: a condition caused by occlusion of one or more of the coronary arteries. life-threatning condition results when myocardial tissue is destroyed in areas of the heart that are deprived of an adequate blood supply due to the occluded vessels. |
|
|
Term
|
Definition
| inflammation of the myocardium may be caused by viral or bacterial infections or may be a result of systemic diseases such as rheumatic fever. also fungal infections, serum sickness or a chemical agent. |
|
|
Term
|
Definition
| inflammation of the pericardium. can be acute or chronic. |
|
|
Term
|
Definition
| an inflammatory disease that may develop as a delayed reaction to insufficiently treated goup A beta-hemolytic stretococcal infection of the upper respiratory tract. |
|
|
Term
|
Definition
| a localized dilatation of an artery formed at a weak point in the vessel wall. this weakened area balloons out with each pulsation of the artery. |
|
|
Term
|
Definition
| an arterial condition in which there is thickening, hardening, and loss of elasticity of the walls of arteries, resulting in decreased blood supply, especially to the lower extremities and cerebrum. this is also called hardening of the arteries. |
|
|
Term
|
Definition
| a condition in which the patient has a higher blood pressure than that judged to be normal. |
|
|
Term
| peripheral arterial occlusive disease |
|
Definition
| obstruction of the arteries (mainly the legs). leading cause of this disease is atherosclerosis, which leads to narrowing of the lumen of the artery. classic symptom is intermittent claudication which is a cramplike pain in the muscles brought on by exercise and relieved by rest. |
|
|
Term
|
Definition
| intermittent attacks of vasoconstriction of the arterioles(causing palor of the fingers or toes) follow by cyanosis and then redness before returning to normal color. initiated by exposure to cold or emotional disturbance. |
|
|
Term
|
Definition
| inflammation of a vein associated with the formation of a thrombus; usually occurs in an extremity, most frequently a leg. |
|
|
Term
|
Definition
| enlarged, superficial veins; a twisted, dialted vein with incompetent valves. |
|
|
Term
|
Definition
| an abnormal circulatory condition characterized by decreased return of venous blood from the legs to the trunk of the body. |
|
|
Term
|
Definition
| a congential heart defect characterized by a localized narrowing of the aorta, which results in increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities. |
|
|
Term
|
Definition
| is an abnormal opening between the pulmonary artery and the aorta caused by failure of the fetal ductus arteriosus to close after birth. is seen primarily in premature infants. |
|
|
Term
|
Definition
| a congenital heart anomaly that consists of four defects: pulmonary stenosis, interventricular septal defect, dextroposition (shifting to the right) of the aorta so that it receives blood from both ventricles and hypertrophy of the right ventricle;names for the french physician, etienne fallot, who first described the condition. |
|
|
Term
| transposition of the great vessels |
|
Definition
| a condition in which the two major arteries of the heart are reversed in position, which results in two noncommunicating circulatory systems. |
|
|
Term
|
Definition
| is any deviation from the normal pattern of the heartbeat. |
|
|
Term
|
Definition
| condition in which the contractions of the atria become extremely rapid, at the rate of between 250 and 350 beats per minute. |
|
|
Term
|
Definition
| atrial fibrillation is extremely rapid, incomplete contractions of the atria resulting in disorganized and uncoordinated twitching of the atria. |
|
|
Term
|
Definition
| is an interference with the normal conduction of electric impulses that control activity of the heart muscle. |
|
|
Term
|
Definition
| a condition in which the ventricles of the heart beat at a rate greater than 100 beats per minute; characterized by three or more consecutive premature ventricular contractions. is is also known as V-tach |
