Murmurs Flashcards
(50 cards)
Which valves cause most disease
Left valves, cause the most disease
Due to higher pressure
Why is function of valves
Ensure that blood is flowing in one direction
Stenosis is what
Narrowing of the valve
Regurgitation is what
Deformed or damaged valves, which allow backflow of blood
Why does left side of the heart cause most disease in adults
Higher pressure, and therefore there is more turbulence,
What is causing murmur, valvular heart disease
Infections, such as rheumatic fever, or endocarditis,
Heart diseases, such as coronary artery disease
Autoimmune diseases such as rheumatoid arthritis
What to do when u first hear a murmur
Assess the location of where it is heard
How loud is it
Does it radiate
Does it change with different positions
Does it change with other maneuvers, breathing or squatting
Two main heart sounds are
S1; and s2 referred to as lub dub
S1 Is the closure of the __ valves
AV MITRAL AND TRICUSPID
S2 is closure of the ______ valves
Semilunar
S3 heart sound is heard when
In early diastole just after S2
Why does an S3 sound occur
From blood rapidly hitting the left ventricle when filling, and is a vibration sound
MCC Cause of S3 in elderly is
CHF
What are other causes of S3
Can be due to dilated cardiomyopathy
**CHF
Or pregnancy
S4 is heard best in _____ diastole before S1
Late
What causes S4 heart sound
Results from a forceful atrial contraction, pushing blood into stiff left ventricle
True or false S4 is always an abnormal finding
True
If u hear S4 heart sound what might u be suspecting
Hypertension or acute MI causing stiff left ventricle
Systolic heart murmurs are heard between
S1 and S2
Systolic murmur can be ejection murmur ______or _______regurgitant murmur _____or _____
Aortic or pulmonic stenosis
Mitral or tricuspid regurgitation
Increase venous return increase intensity of most murmurs except for
Hypertrophic cardiomyopathy and mitral valve prolapse
The mvp hates conforming to the rule
Diastolic murmur hears between _____ and ___
S2 and S1
Diastolic murmur mnemonic
Ms prarts died
Mitral stenosis
Pulmonary regurgitation
Aortic regurgitation
Tricuspid stenosis
Died, diastolic
What maneuvers increase venous return
Squatting
Raising legs
Inspiration
