osis abnormal condition
pathy disease
plasty surgical repair/reconstruction
clerosis hardening
stasis stopping/controlling
stenosis narrowing
atria upper chambers of the heart
ventricles lower chambers of the heart
septum muscular wall which divides the heart muscle into right and left side
epicardium outer layer of the heart
myocardium middle, thick, muscular layer of the heart
endocardium inner layer of the heart
sinoatrial node (SA node) the pacemaker where the electrical impulse of the hear originates
atrioventricular node (AV node) located between the right atrium and right ventricle
Bundle of His transmission of electrical impulses to both ventricles of the heart
circulation movement of blood through vessels throughout the body
pulmonary circulation circulation between the heart and the lungs
systemic circulation circulation of blood between the heart and the rest of the body
superior vena cava one of the two largest veins of the body
inferior vena cava one of the largest veins in the body
tricuspid valve valve located between the right atrium and right ventricle
chordae tendinae strong fibrous bands that attach the corners of the heart valves to the muscles of the lower heart chambers
papillary muscles are attached to the undersurfaces of the valve cusps, also contract pulling open the valve
pulmonary valve a valve consisting of three semilunar cusps separating the pulmonary trunk from the right ventricle
pulmonary artery transports deoxygenated blood from the right ventricle to the lungs
oxygenation process by which waste filled blood is exchanged for oxygen rich blood in the lungs
pulmonary vein vessel that returns oxygenated blood to the heart
bicuspid valve valve between the left ventricle; also know as the mitral valve
aortic valve valve between the left ventricle and the aorta
aorta largest artery on the body
arteries carry oxygen-rich blood away from the heart to various parts of the body
arterioles small vessels branching off from ateries
capillaries small vessels branching off from arterioles
sphygmomanometer instrument used to measure blood pressure
stethoscope an instrument used to hear and amplify the sounds made by the heart, lungs, and other internal organs
systole (systolic blood pressure) pressure in the vessels as the heart is contracting
diastole (diastolic pressure) the pressure in the vessels when the heart is at rest, between contractions
cardiology the branch of medicine that studies the function and disorders of the heart
cardiologist a physician who specializes in diseases and disorders of the cardiovascular system
electrocardiogram (EKG, ECG) graphic record of the electrical activity of the heart
angina pectoris chest pain related to stress, exercise, extreme cold; constriction of blood vessels
angiography x-ray picture of the heart blood vessels
arteriosclerosis hardening of the arteries
arteriosclerotic heart disease heart disease caused by hardening of arteries
atherosclerosis narrowing/hardening of arteries as fat deposits on walls of vessels
cardiac arrest sudden stoppage of the heart
cardiac catherization procedure where a catheter is guided through a vein or artery into the hear and x-ray pictures are taken
cardiopulmonary resuscitation (CPR) life saving procedure used after heart stoppage, involves artificial respiration and manual external compression of the heart
congestive heart failure disease process in which the heart cannot pump enough blood to meet the needs of the tissues
coronary artery bypass graft (CABG) surgical procedure whereby a blocked artery is bypassed using a vein
coronary artery disease (CAD) abnormal condition which can affect the arteries of the heart
echocardiogram procedure using sound waves to visualize the heart
hypertension high blood pressure
myocardial infarction (MI) heart attack; insufficient blood supply to heart muscle causes death to the affected area
vasocontriction narrowing of a vessel due to constriction
bradycardia slow heart rate
bundle branch block (BBB) electrical impulse to either right or left bundle branch is interrupted
fibrillation atria or ventricles rapidly and incompletely contract due to chaotic electrical activity
palpitation fluttering/abnormal throbbing of heart
paroxysmal atrial tachycardia (PAT) begins and ends suddenly, where there is a rapid atrial contraction
premature atrial contraction (PVC) ventricles contract too early
premature atrial contraction (PAC) atria contracts too early, before anticipated time
tachycardia rapid heart rate/above 100 per minute
ventricular fibrillation ventricles contract randomly without coordination, life threatening
ventricular tachycardia ventricles contract rapidly at about 150-200 times per minute
