Heart Sounds/ Murmurs Flashcards
In what murmur can you see head-bobbing, water hammer pulse, or femoral bruits?
aortic regurgitation
What characterizes aortic stenosis?
crescendo-decrescendo murmur
btw S1-S2
Old-SAD
radiates UP to carotids
What does S3 sound like?
Ken-tuckee
blood filling relaxed and empty ventricle
hear right after S2!
What creates the 4th heart sound?
atrial contraction = result of the last little bit of blood being squeezed into the ventricles
normal in children, not generally heard in a normal adult
hear right before S1!
What does the LAD/ anterior interventricular A supply blood to?
Part of AV node
part of His bundle
R bundle branch
anterior fascicle of left bundle branch
What is the first heart sound?
closure of the AV valve –> blood rushing against it
What action decreases aortic stenosis murmors?
increases?
valsalva/standing - decreases
rapid squating - increases
What creates the 3rd heart sound?
blood rushing into the ventricle during the rapid filling phase (AV valves open)
*normal in children, but might not be heard in normal adults
What is the mnemonic to remember the heart assessment points?
All Physicians Take Money Aorta = R 2nd intercostal space Pulmonic area = L 2nd intercostal space Erb's point = L 3rd intercostal space Tricuspid = L 4th intercostal space Mitral = 5th intercostal space, L midclavicular
What murmur is associated w/ connective tissue disorders and marfan’s?
aortic regurgitation
What causes a systolic murmur?
either blood is moving back into the atria, caused by regurgitation
blood is having a hard time moving in the direction it should be moving in (can’t get into the aorta/pulmonary A
What characterizes mitral regurgitation?
“Rheu-mitral”
radiates to axilla
best heard at apex
holosystolic (same loudness throughout) btw S1 and S2
What characterizes mitral stenosis?
the Operating System is MicroSoft
opening snap, rheumatic fever hx
loud, soft, then loud before S1
What is the second heart sound associated with?
closing of aortic and pulmonary valves –> blood backflows and bounces off closed valves
What characterizes a mitral valve prolapse?
midsystolic “click”
associated w/ young women w/ psychiatric history
