atherosclerosis a form of arteriosclerosis (hardening of the arteries)characterized by fatty deposits building up within the inner layers of the walls of larger arteries
hepathomegaly enlargement of the liver
epicardium the inner layer of the pericardium, which is the double-folded membrane that encloses the heart
endocarditis inflammation of the inner lining of the heart
edema the localized or gerneralized collection of fluid within the body tissues,causing the area to swell
dysrhythmia abnomral rhythm
diastole the period of relaxiation of the heart, alternating with the contraction phase is known as systole
dependent edema a fluid accumaltion in the tissues influenced by gravity, usually greater in the lower extermities than in tissue levels above the heart
cusp any one of the small flaps on the valves i=of the heart
cornary artery one of a pair of arteries that branch from the arota. the cornary arteries and their branches supply blood and oxygen to the heart muscle(myocardium)
claudication cramplike pains in the calves of the legs caused by poor circulation to the muscles of the legs;commonly assocaiated with artherosclerosis
carditis inflammantion of the heart muscles
bruit an abnormal sound or murmur heard when listening to a cartoid artery, organ or gland with a sethoscope for example during ausculation
benign noncancerous; not progressive
nocturia urination at night
occlusion closure, or state of being closed
orthopena an abnormal condition in which a person sits up straight or stands up to breathe comfortably
pacemaker the SA mode (sinoatrial) of the heart located in the right atrium. it is responsible for initiating the heartbeat, influencing the rate and rhythm of the heart beat
the cardiac pacemaker (artifical pacemeaker) is an electric apparatus used for maintaining a normal heart rhythm by eclectically stimulating the heart muslce to contract
palpable detectable by touch
prophylatic an agent that protects against disease
palpiation a pounding or racing of the heart, associated with normal emotional reponses or with disorders
perciaridal pertaining to the pericardium
pericardium the dounle membranous sac that encloses the heart and the origins of the great blood vessels
petechiae small. purplish, hemorrhagic spots on the skin; may be due to abnormality in the blood-clotting mechanism of the body
pitting edema is swelling, usually of the skin of the extremities, that when passed firmly with a finger will maintain the dent produced by the finger
pulmonary artery one of a pair of arteries that transports deoxygentaed blood from the right ventricle of the heart to the lungs for oxygenation. the pulmonary arteries are the only arteries in the body to carry deoxygenated blood
pulmonary circulation the circulation of deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation and back to the left artium of the heart; that is,from the heart, to the lungs, back to the heart
Homan's Sign pain felt in the calf of the leg, or behind the knee, when the examiner is purposely dorsiflexing the foot of the patient(bending the toes upward toward the foot) if the patient feels pain,it is called a positive Homan's sign(indicating thrombophlebitis
hyperlipidemia an excessive level of fats in the blood
hypertension elevated blood pressure persistently higher than 135/85 mmHg;high blood pressure;also known as arterial hypertension
hypotension low blood pressure;less than normal blood pressure reading
infarction a localized area of necrois (death)in tissue,a vessel,an organ,or a part resulting from a lack of oxygen(anoxia)due to interrupted blood flow to the area
ischemia decreased supply of oxygenated blood to a body part or organ
lesion a wound,injury or any pathological change in body tissue
lipid any of a group of fats or fatlike substance found in the blood. examples within an artery,vein,acids, triglycerides
lumen a cavity or the channel within sn y organ or structure of the body, the space within an artery,vein,intestine or tube
malaise a vague feeling of body weakness or discomfort ofter indicating the onset of an illness or disease
mediastinum the area between the lungs in the chest cavity that contains the heart, aorta,trachea,esophagus and bronchi
murmur a low-pitched humming or fluttering sound, as in a "heart murmur" heard on ausculation
myocardium the middle muscular layer of the heart
pulmonary vein one of the four larger veins(two from each lung)that returns oxygenated blood from the lungs back to the left atrium of the heart.the pulmonary veins are theonly veins in the body to carry oxygenated blood
SA node sinoatrial node;pacemaker of the heart
septum a wall,or partition, that divides or separates two cavities. the interatrial septum separates the right and left atria, the atrioventricular septum separates the atria and the ventricles & the interventricular septum separates the right & left ventricles
serum sickness a hypersensitivity reaction that may occur 2 to 3 weeks after administration of an antiserum. symptons-fever,enlargement of the spleen(splenomegaly) swollen lymphnodes,joint pain and skin rash
vegation an abnormal growth of tissue around a valve
vaxoconsrtiction narrowing of the lumen of a blood vessel
