cardiac Flashcards
v tach
abnormal heart rhythm; when ventricles serve as pacemaker of the heart
left sided heart failure
blood backs up into the lungs
left sided heart failure characteristics
crackles
dyspnea
decreased O2 sat
S3 is common
right sided heart failure
fluid backs up into the body
right sided heart failure characteristics
edema in extremities
jugular vein distention
S3
systolic murmur
causes of coronary artery disease
ischemia
infarction
coronary artery disease (CAD) treatments
angioplasty
CABG
S1
closure of AV valves
heard best at apex
beginning of systole
S2
closure of semilunar valves
heard best at base
beginning of diastole
S3
vibration heard when blood passively flows into ventricle
heard AFTER S2
heard best at apex
may be normal in young adults/athletes
may indicate CHF
S4
vibration heard when blood is ejected into the ventricle from atrial contraction
heard immediately BEFORE S1
heard best at apex
may indicate CAD, HTN
systolic murmur
separates S1 & S2
lub-swish-dub
diastolic murmur
before OR after S1 & S2
swish-lub-dub/lub-dub-swish
which side of the stethoscope do you use to hear a pericardial friction rub?
diaphragm
pericardial friction rub
pericardium inflamed due to pericarditis
murmur intensity grading scale
1-6
valve disease
acquired or congenital disorder characterized by stenoic valve (does not open completely) or incompetent valve (does not close completely)
account for most acquired VHD
rheumatic fever
endocarditis
treatments for coronary artery disease
stents
CABG
angina pectoralis
chest pain due to ischemia of myocardium
what causes coronary artery disease?
atherosclerosis
what can diagnose CAD?
heart cath
stress test
