Cardiovascular System (Chapter 10) Flashcards
chest pain usually caused by an insufficient supply of blood to the heart
angina pectoris
abnormal contractions of a blood vessel wall
angiospasm
narrowing of a blood vessel
angiostenosis
any loss of rhythm in the heartbeat
arrhythmia
abnormally slow heart rate, usually under 60 beats per minute
bradycardia
sensation of pain in the heart
cardiodynia
condition that originates in the heart
cardiogenic
abnormal hypertrophy of the heart
cardiomegaly
blue coloration of the skin & mucous membranes; caused by oxygen deficiency
cyanosis
disturbance or abnormality of the heart’s normal rhythmic cycle
dysrhythmia
experience of pounding, racing, or skipping of the heartbeat
palpitation
fast heartbeat
tachycardia
bulging of an arterial wall caused by a congenital defect or an acquired weakness of the arterial wall produced as blood is pushed against it
aneurysm
inflammation of the heart & blood vessels
angiocarditis
tumor that arises from a blood vessel
angioma
rupture of an artery
arteriorrhexis
hardening of the arteries; the artery walls lose their elasticity & become brittle
arteriosclerosis
narrowing of an artery due to the deposition of a fatty plaque along the internal wall
atherosclerosis
ASD: congenital condition characterized by an opening in the septum that separates the right & left atria, allowing blood to pass between the atria
atrial septal defect
defect, usually congenital, that alters the structure of both an atrium & a ventricle
atrioventricular defect
cessation of heart activity
cardiac arrest
acute compression of the heart due to the accumulation of fluid w/in the pericardial cavity
cardiac tamponade
general disease of the heart muscle
cardiomyopathy
inflammation of the heart valves
cardiovalvulitis
limp when walking, caused by poor circulation
claudication
congenital disease in which the aorta is narrowed; causes reduced systemic circulation & fluid accumulation in the lungs
coarctation of the aorta
CHF: chronic condition characterized by the inability of the left ventricle to pump enough blood through the body to adequately supply systemic tissues AKA left ventricular failure
congestive heart failure
chronic enlargement of the right ventricle that results from congestion w/in the pulmonary circulation AKA right ventricular failure
cor pulmonale
CAD: generalized condition of the arteries of the heart, characterized by a reduction of blood flow to the heart wall, most common is atherosclerosis
coronary artery disease
blockage of an artery that supplies the heart; often due to atherosclerosis
coronary occlusion
DVT: abnormal presence of stationary blood clots w/in the deep veins of the leg
deep vein thrombosis
blood clot or foreign particle that moves through the circulation, which can produce a severe circulatory restriction when it becomes lodged in an artery
embolism
inflammation of the endocardium; common cause is bacterial infection
endocarditis
uncoordinated, rapid contractions of the ventricles or atria
fibrillation
HA: acute episode during which the myocardium is deprived of blood flow leading to tissue death AKA myocardial infarction (MI)
heart attack
interference w/ the normal electrical conduction of the heart; often the result of a sudden reduction of blood flow that affects the SA or AV node
heart block
