Cardiovascular Flashcards
(206 cards)
relaxation & filling
diastole
contraction & ejection of blood
systole
sounds made by turbulent BF
murmur
palpable murmur
thrill
rhythmical throbbing of arteries as BF through
against bony prominence
pulse
difference in rate between apical & radial/peripheral pulses
pulse deficit
sound made by closure of atrioventricular valves (mitral, tricuspid)
S1
S1 occurs when?
end of diastole
beginning of systole
sound made by closure of semilunar valves (aortic, pulmonic)
S2
S2 occurs when?
end of systole
beginning of diastole
explain cardiac cycle including events, valve closure, sounds
SYSTOLE
- atria relax
- AV valves close (S1) — SL valves open
- ventricles contract
- blood moves out into pulmonic & aortic arteries
DIASTOLE
- ventricles relax
- SL valves close (S2) — AV valves open
- atria contract
- blood moves into ventricles
inflammation/pain from inside joint
arthralgia
particle moving through vessels
embolus
blood clot in vessel
thrombus
moving blood clot
thromboembolus
cardiac output =
stroke volume x HR
pathway of electrical conduction through heart (5)
Sinoatrial node (SA) → atrioventricular node (AV) → bundle of HIS → L & R bundle branch → Purkinje fibers
A normal event becomes audible
abnormal heart sounds
3 potential causes of a murmur
- Increased volume - ex pregnancy
- Abnormal valve
- Abnormal flow b/t structures
why can pregnancy cause a murmur?
blood volume ↑ 45% during pregnancy

S3
Ventricular gallop
when does S3 occur
early diastole (after S2)
etiology of S3
impact of incoming blood against a distended ventricle wall
(extra compliant ventricular wall)
How to hear S3
