Flashcards in test 2 pt.2 Deck (57):
1

in the p wave..

the atria is contracting; sending the electrical impulse
depolarization

2

pr segment

identifies the isoelectric line; impulse is traveling

3

pr interval

length of time the impulse is being sent from sa node to perkinges fibers; shouldn't be longer than .20seconds

4

t wave

repolarization of ventricles

5

st segment should

come back to baseline

6

is st segment goes up what does this mean

MI; injury

7

u wave can represent

hypokalemia; low potassium

8

av node is the

gatekeeper. holds onto impulse for atrium to do one last squeeze which is 25% of cardiac output

9

t wave inversion

ischemia

10

tissue death; abnormal q wave

infarction

11

peaked t wave

hyperkalemia high potassium

12

stretch on ventricle at end of diastole

preload

13

pressure the ventricles outcome to inject blood out

after load

14

primary hyperlipidemia

caused by genetics

15

secondary hyperlipidemia

result from another disease

16

feb 1

go red for women; cardiac health month; 1 in 5 will die of cardiovascular

17

-statins are for

hypercholesterolemia

18

why should statins be given at night

cholesterol is produced and liver works the most

19

artierosclerosis

hardening of arteries

20

atherosclerosis is mainly what

fats cause thickening of vessels

21

pain in calf when walking

claudication

22

another manifestation of pad

thinning of skin; shining ; lack of hair on lower extremities

23

primary raynauds is seen in who

healthy young women

24

secondary raynauds is

already been injury to areas ; frostbite

25

dissolves a dangerous clot

thrombolytics

26

substernal back and neck pain, dyspnea, stridor, hoarseness

thoracic aneurysms

27

once you palpate an abdominal aneurysm what do you not do

dont go back and palpate again, could rupture.

28

marfan syndrome is very common to affect

the heart ; aortic valve disorder

29

hypertensive crisis

180/120

30

cardiac disease

imbalance of oxygen supply and oxygen demand

31

angina pectoris

chest pain

32

stable angina will last how long

less than 20 minutes

33

3 types of acute coronary syndrome

unstable angina pectoris
NSTEMI- did not go through all heart layers
STEMI- did go through all heart layers

34

last longer than 20 minutes and chest pain is not relieved by sitting them down after an activity; occurs with activity or rest

unstable angina

35

chest pain happen at night caused by vasospasms

Variant (Prinzmetal’s) angina

36

unstable angina non modifiable

rash
race, age, sex, hereditary (AA)

37

unstable angina modifiable

cholesterol, smoking, physical inactivity, hypertension, serum homocysteine,

38

why would you give morphine

for pain; vasodilator, helps with breathing

39

reversal of narcotic

narcan

40

why give a beta blocker to treat ACS

beta receptors b1-heart, b2-lungs; chemical that stimulates beta receptor epi-increase oxygen demand, heart rate

41

reversal for heparin

protamine sulfate ; coagulates

42

you can ABSOLUTELY not have a thrombolytic if

you recently had surgery; stroke within past 2 months; recently pregnant

43

if a girl is mense aka on period will you give a thrombolytic

yes

44

most common cause of endocarditis

staphococcal

45

infective endocarditis

osler nodes- hurts
janeway lesions

46

rheumatic heart disease occurs after WHAT

GROUP A STREP

47

how do you find out if a patient has rheumatic heart disease

throat assessment -white patches, swollen tonsils and lymph nodes

48

right sided heart failure

peripheral edema - swelling in legs
mesentary congestion - ascites- swollen belly
jugular vein distention
shortness of breath
fatigue
SYSTEMIC SIGNS AND SYMPTOMS

49

left sided heart failure

pulmonary edema - wet lungs (crackles)
decrease oxygen
hemophysis- pink froth sputum *only on left side**

50

only reversible myocardiopathy

taco subo

51

mitral valve stenosis is caused by what

rheumatic fever (untreated strep) and its a lifelong disorder

52

3 manifestations of acute pericarditis

chest pain, friction rub, ecg changes

53

how to treat acute pericarditis

aspirin or NSAIDS, if dont work Colchicine

54

Cardiac Tamponade: Becks Triad

jugular venous distension, low bp, muffled heart sounds

55

is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied)

hypertropic cardiomyopathy

56

hypertropic cardiomyopathy treatment

beta blocker
calcium channel blocker

57

#1 contraindication for thrombolytic

prolonged cpr
