commonly asymptomatic
irregular pulse with no pattern to irregularity asystole(不全収縮)
apnea(a- means without, -pnea means breathing)
cyanosis(cyan means blue, -osis means abnormal condition)
no palpable blood pressure
pluselessness

ventricular fibrillation also known as V fib,
apnea
no palpable blood pressure
pulselessness

ventricular tachycardia(tachy- means rapid, car- means heart, and -ia means abnormal cindistion)

Coronary Artery disease

.Atherosclosis (ather/o means plaque or fatty substance and -sclerosis means abnormal harding)

.ischemia is a temporary deficiency in blod supply due to either the constriction or the obstruction of a blood vessel. (isch means to hold back and -emia means blood).

ischemic heart disease

.angina pectoris also know as sngina, = ischemia of teh heart muscle.
angina(chest pain) that may be substernal, crushing, or compressing; may radiate to arms, jaw, or back; usually lasts 3 to 5 miniutes

bllod chemistry tests; increase cholesterol(decrease high-density lipoproteins, increase low-dentisy lipoproteins).

EKG or holter monitoring show ST-segment depression and T-wave inversion during an anginal episode.

.myocardial inafarction also know as a heart attack
is the occlusion(blockage=閉塞) of one or more coronary arteries resulting in an infract of the affected myocardium.

Cardovascular System 1 〜Medical Terminology 〜


major structure related combining forms
heart carid/o cardi/o
Blood vessels angi/o, vas/o
.arteries arteri/o
.capillaries capil/o
.veins phleb/o, ven/o
Blood hem/o, hemat/o


words parts

cardiovascular
vascul means blood vessels
-ar means pertaning to

pericardium (peri-cardi-um) 心膜
peri- means surrounding
-um means singular noun ending

walls of the heart
three layers
epicardium epi- means upon 心外膜
myocardium          心筋層
endocardium endo- means within  心内膜

the blood supply to the miocardium
coronary arteies and veins

the heart chambers
the atria(AY-tree-ah) two upper chmbers of the heart.
(singular;atrium)

the ventricles(ven-trih-kuhls) two loewrchambers ofthe heart

the heart valves
four valves; the tricuspid(三尖弁), plumonary semilunar(肺動脈弁), mitral(僧帽弁), and aortic semilunar (大動脈弁)valves.

blood flow through the heart
the right atrium(RA) recives oxygen-poor blood through superior & inferior vena cavae. blood flow out of the RA through the tricupid valve into the right ventricle.

right ventricle(RV) oxygen poor blood through the pulmonary semiluar valve and into plumonary artery, wihch is carries it to the lungs.

the left atrium(LA) recives oxygen-rich blood from the lungs through teh four plumonary veins(left & right) the blood flows out of the LA, through the mitral valve, and into the left ventricle.

the left venticle(LV) recieves oxygen-rich blood from the left atrium.
blood flow out the aortic semilunar valve and, into the aorta, which carries ot to all parts of the body, except the lungs.

oxygen -poor blood is returned by venae cavae to the right atrium and the cycle continues.


pulse and blood pressure

systlic pressure, which occurs when the ventricles contract, is the highest pressure against the walls of the blood vessels.

diastolic pressure, which occures when the ventricles are relaxed, is the lower pressure ainst teh walls of the blood vessels.

the blood

formed elements of the blood

erythrocytes(eh-RITH-roh-sights), also as know as red blood cells(RBCs)
erythr/o means red and -cytes means cells

hemoglobin

leukocytes, also as know as white blood cells(WBCs)
luek/o means white

thrombocytes, the smallest formed elements fo the blood
thromb/o means clot also know as platelets
