Murmurs Flashcards
order of all possible heart beats
S4, S1, S2, S3
S4
beating against a stiff ventricle
not always pathologic because aging makes ventricle stiffer
S1
closing of mitral and tricuspid valve
starts systole
S2
closing of aortic and pulmonic valves
end of systole when ventricular P < aortic/pulm P
order of valves opening and closing
MVc TVc , PVo AVo \ AVc PVc , TVo MVo
physiological split of S2
when breathing in
due to incr venous return to right heart
aortic regurgitation (aortic insufficiency)
incr carotid pulse (aorta is arterial structure)
S1, S2, shhh
aortic valve just closed but blood going back in diastole
aortic stenosis
mid-systolic
between S1 and S2
S1, shh, S2
systolic murmur at right upper sternal border
after closure of mitral and tricuspid
and open of aortic and pulmonic
mitral regurg
mid-systolic
between S1 and S2 after mitral closes
“blowing” murmur at apex
obstructive left circumflex can also present with mitral regurg
acute mitral regurg
incr HR to compensate
mitral stenosis
think rheumatic heart disease
opening safter S2
going against high pressure mitral valve
diastolic murmur
carotids pulsating because so much blood in LA
S3 not as loud = generated by atria
fixed Split s2
no change with breathe in or out
rubs
interaction btwn pericardium and heart below
gallop
S3 or S4
murmur
flow = regurg and stenosis
