Week 5 - CV 2, PV, and Lymphatics Flashcards
ROS Question
Any swelling, pain, or discoloration in your arms or legs?
Systole is when?
Interval between S1 and S2
Diastole is when?
S2 and S1
When is S1 heard?
Just before the carotid upstroke
When is S2 heard?
Following the carotid upstroke
Where is S1 louder than S2?
At apex
Where is S2 louder than S1?
Base
What sounds are listened to by the diaphragm?
High-pitched sounds
What 3 sounds can be heard with the diaphragm?
- S1 and S2
- Aortic and mitral regurgitation
- Pericardial friction rubs
What do we listen to with the bell?
Low-pitched sounds
What 2 things can we hear from the bell?
- S3 and S4
2. Murmur of mitral stenosis
How do we apply the bell?
Lightly
2 specific times when S1 can be accentuated?
- High cardiac output
2. Mitral stenosis
2 specific times when S1 can be diminshed?
- Mitral valve is calcified and relatively immobile
2. L ventricular contractility is markedly reduced
Where do we listen for splitting in S2?
2nd or 3rd L interspace
Where do we see pathologic splitting a lot?
Atrial septal defect
Where do we see early systolic ejection sounds?
Aortic valve disease from congenital stenosis
What do we often see systolic clicks?
Mitral valve prolapse
What is “Opening Snap”?
Very early diastolic sound usually produced by the opening of a stenotic mitral valve
Where is “Opening Snap” heard best?
Just medial to apex
Where will we often detect PHYSIOLOGICAL S3?
- Children and in young adults to the age of 35 or 40
2. Last trimester of pregnancy
When does S3 occur?
Early in diastole during rapid ventricular filling
Is an S3 in adults over 40 pathological? What is it caused by?
Yes; high pressures and abrupt deceleration of inflow
What is “Kentucky”?
Involved in S3. Gives rise to the term gallop from the cadence of 3 heart sounds, especially rapid heart rates that sound like Kentucky
What is S4 commonly due to?
Increased resistance to ventricular filling following atrial contraction
What is “Tennessee”?
Left sided S4 heard best at the apex in the L lateral position
What is a “Summation Gallop”?
A patient that has both S3 and S4 producing a quadruple rhythm. At rapid rates S3 and S4 may merge into one extra large heart sound called a summation gap
What do we do for a heart murmur?
- Timing (S or D?)
- Where is it loudest
- Shape of murmur
- Maneuver the patient
- Identify associated features (quality of S1/2, presence of extra sounds)
- Intensity
2 terms associated with the timing of heart murmurs
- Pansystolic murmur
2. Midsystolic murmur
