Q

blood pressure

A

pressure exerted by the blood against the walls of arteries/veins
- written as a ratio of 120/80
- high bp (hypertension) 140/90

Q

systole

A

ventricular contraction
- top number
- pulmonary and aortic valves are open
-increase in blood volume = increase in pressure

Q

holter monitor

A

portable ekg that monitors electrical impulses through the heart

20
Q

EKG

A

measures electrical signals through the heart

21
Q

defibrillation

A

shaking the heart to stop it so it can correct itself and beat normally
-via AED

22
Q

pacemaker

A

internal defibrillator and regulates heart rate

23
Q

coronary artery bypass graft

A

bypassing blocked artery with another artery taken from somewhere else in patient
- “detour”
- “making another artery”

24
Q

heart transplant

A

treatment for CHF

25
Q

balloon angioplasty w/stent

A

use balloon to open up clogged artery
- minimally invasive
- if anything reclogs, no more stents

26
Q

angiotesin-converting (ACE) inhibitor

A

dilates blood vessels

27
Q

anticoagulant

A

reduces blood clotting

28
Q

antihypertensive

A

reduce blood pressure

29
Q

antiarrythmic

A

restores rhythm to heart

30
Q

calcium channel blocker

A

dilates blood vessels

31
Q

diuretic

A

makes kidneys urinate out excess fluid

32
Q

digitoxin/digitalis

A

strengthens the contraction of the heart

33
Q

aneurysm

A

localized enlargement of an artery
- result of a weakened arterial wall from plaque
-blood flow/ circulation not affected

34
Q

angina

A

severe chest pain due to ischemia of myocardium, usually happens during exertion

35
Q

congestive heart failure (CHF)

A

end stage heart disease
- ventricles are so damaged, they can’t pump blood effectively anymore

36
Q

atherosclerosis

A

fat plaque (atheroma) that adheres to and hardens arteries, causes arteriosclerosis (narrowing of artery)

37
Q

arrhythmia

A

absence of rhythm in heartbeat
-can result in fibrillation
- early childhood - mid 20’s
- electrical/nervous system problem

38
Q

bradycardia

A

slow heart rate

39
Q

tachycardia

A

fast heart rate

40
Q

shock

A

sudden drop in bp resulting in inadequate venous return
- blood is not coming back into vena cava
- could be caused by hemorrhage

41
Q

embolus

A

circulating blood clot
- can cause instant death if in pulmonary
- most vulnerable people are post surgery
-anesthesia can cause blood to pool

42
Q

thrombus

A

blood clot that got stuck inside a blood vessel

43
Q

heart murmur

A

abnormal heart sound due to a valve problem
- blood can regurgitate/backwash
- valve replacement surgery can be done with pig/cow valve

44
Q

auscultation

A

listening to heart via stethoscope

45
Q

hypertension

A

diagnosis of high blood pressure

46
Q

myocardial infarction

A

heart attack, blockage of a coronary artery which results in death of myocardium
- least harmful is in the right distal coronary artery

47
Q

cholesterol

A

main purpose is to repair blood vessels
HDL + LDL should be less than 200
LDL goes to repair damaged blood vessel, not enough HDL to bring it out will form plaquing of WBC and LDL in veins
