Flashcards in Chapter 11: Need to Know Terms Deck (72):
1

aorta

largest artery in the body

2

arteriole

small artery

3

artery

largest type of blood vessel; carries blood away from the heart to all parts of the body

4

coronary arteries

blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle

5

deoxygenated blood

blood that is oxygen-poor

6

diastole

relaxation phase of the heartbeat (Greek diastole, dilation)

7

electrocardiogram

record of the electricity flowing through the heart. electricity is represented by waves or deflections called P, QRS, or T

8

endocardium

inner lining of the heart

9

endothelium

innermost lining of blood vessels

10

mitral valve

value between the left atrium and the left ventricle; bicuspid valve

11

murmur

abnormal swishing sound caused by improper closure of the heart valves

12

myocardium

muscular, middle layer of the heart

13

septum
septa

four chambers of the heart separated by partitions

14

sphygmomanometer

instrument to measure blood pressure

15

systole

contraction phase of the heartbeat. (Greek systole, contraction)

16

tricuspid valve

located between the right atrium and the right ventricle; it has three leaflets, or cusps

17

valve

structure in veins or in the heart that temporarily closes an opening so that blood flows in only one direction

18

vein

thin-walled vessel that carries blood from body tissues and lungs back to the heart. veins contain valves to prevent backflow of blood

19

ventricle

one of two lower chambers of the heart

20

venule

small vein

21

auscultation

listening to the internal sounds of the body

22

arrhythmias

abnormal heart rhythms

23

flutter

rapid but regular contractions, usually of the atria

24

fibrillation

very rapid, random, inefficient and irregular contractions of the heart (350 or more beats per minute)

25

atrial fibrillation (AF)

most common type of cardiac arrhythmia

26

palpitations

uncomfortable sensations in the chest from missed heartbeats

27

ventricular fibrillation (VF)

electrical impulses move randomly throughout the ventricles

28

implantable cardioverter-defibrillator (ICD)

small electrical device that is implanted inside the chest to sense arrhythmias and terminate them with an electric shock

29

congestive heart failure (CHF)

heart is unable to pump its required amount of blood

30

congenital heart disease

abnormalities in the heart at birth

31

CABG

coronary artery bypass grafting

32

PCI

percutaneous coronary intervention

33

endocarditis

inflammation of the inner lining of the heart

34

MVP

mitral valve prolapse

35

bruit

abnormal blowing or swishing sound heard during auscultation of an artery or organ

36

thrill

vibration felt over an area of turmoil in blood flow

37

aneurysm

local widening (dilation) of an arterial wall

38

AAA

abdominal aortic aneurysm

39

DVT

deep vein thrombosis

40

PAD

peripheral arterial disease

41

angina

chest pain resulting from myocardial ischemia

42

cardiac arrest

sudden, unexpected stoppage of heart action, often leading to sudden cardiac death

43

embolus
emboli

clot or other substance that travels to a distant location and suddenly blocks a blood vessel

44

infarction

area of dead tissue

45

occlusion

closure of a blood vessel due to blockage

46

pericardial friction rub

scraping or grating noise heard on auscultation of the heart

47

vegetations

clumps of platelets, clotting proteins, microorganisms, and red blood cells on diseased heart valves

48

BNP Test

measurement of BNP ( brain natriuretic peptide) in blood

49

lipid tests (lipid profile)

measurement of cholesterol and triglycerides (fats) in a blood sample

50

lioprotein electrophoresis

lipoproteins (combinations of fat and protein) are physically separated and measured in a blood sample

51

angiography

x-ray imaging of blood vessels after injection of contrast material

52

cardiac catheterization

thin, flexible tube is guided into the heart via a vein or an artery

53

electrocardiography (ECG)

recording of electricity flowing though the heart

54

(ECG)

electrocardiography

55

Holter monitering

an ECG device is worn during a 24-hour period to detect cardiac arrhythmias

56

endarterectomy

surgical removal of plaque from the inner layer of an artery

57

PCI

percutaneous coronary intervention

58

AF, a-fib

atrial fibrillation

59

BP

blood pressure

60

CABG

coronary artery bypass grafting

61

CAD

coronary artery disease

62

CCU

coronary care unit

63

CHF

congestive heart failure

64

CPR

cardiopulmonary resuscitation

65

DVT

deep vein thrombosis

66

ECG or EKG

electrocardiography

67

echocardiography

68

ETT

exercise tolerance test

69

MI

myocardial infarction

70

MVP

mitral valve prolapse

71

SOB

shortness of breath

72

SVT

supraventricular tachycardia; rapid heartbeats arising from the atria and causing palpitations, SOB, and dizziness
