Cardiovascular Exam Flashcards
What are the AV valves?
Tricuspid
Mitral
What are the semilunar valves?
Aortic
Pulmonic
What are the locations of sounds on PR to help identify valve or chamber origin?
Which is louder, semilunar or AV valves?
Semilunar
What is heard well in the 2nd right interspace?
aortic area
What is heard well in the 2nd left interspace?
pulmonic area
What area is well heard from the lower left sternal border?
The tricuspid area
What is the area best heard from the apex?
Mitral Area
Diastole =
relaxation of ventricles (filling) first, then final 1/3 is atrial contraction
Lub is ___. Whis is the closure of what valves?
S1
Left side - mitral valve
Right side - tricuspid valve
Compare the mitral and tricuspid closure sounds
oMitral
§Louder
§Location: apex2.Right side
oTricuspid
§Softer
§Location: LLSB
S2 is ____. Is due to closure of what valves?
Dub
Aortic (A2)
Pulmonic (P2)
May hear splitting with which sound?
S1
Compare S2 aortic and pulmonic valve sounds
1.Left side
oAortic (A2)
§Louder
§Heard best R 2nd ICS
2.Right side
oPulmonic (P2)
§Softer
§Heard best L 2nd ICS
In what populations might you hear an S3?
Child/young adult
Who might you hear an “S3 gallop”?
Older adult
S3 comes directly after….
S2
S4 comes directly before…
S1
S4, (atrial gallop) marks ____ and is…
Atrial contraction
Always pathological
What is the duration of murmurs?
Longer duration that heart sounds
What are the two types of valvular pathology we covered?
Stenotic
Regurgitant/insufficiency
Describe stenotic murmur
what is an example?
- Narrowing of valvular orifice
- Example: aortic stenosis
Describe regurgitant/insufficiency murmurs
What is an example?
- Fails to close fully allows blood to leak back
- Example: aortic regurgitation
How should we describe murmurs?
(7 things)
- •Timing: Systolic/diastolic
- •Shape: Crescendo, decrescendo, etc.
- •Location: Heard best where?
- •Radiation: hear murmur other places (carotids, axilla, etc)
- •Intensity: Grade-6 point scale
- •Pitch: High, medium or low
- •Quality: Blowing, harsh, rumbling, musical, etc.
Describe murmur grading
- 1: very faint, heard only after listener “tuned-in”
- 2: quiet but immediately heard with stethoscope on chest
- 3: moderately loud
- 4: loud with palpable thrill
- 5: very loud with thrill may be heard with stethoscope partially off chest
- 6: very loud with thrill, may be heard with stethoscope entirely off chest
What is a grade 4 murmur?
•4: loud with palpable thrill
Grade 5 murmur?
•5: very loud with thrill may be heard with stethoscope partially off chest
