24
Q

At what heart rate is Diastole longer than Systole?

A

HR < 120

25
Q

What causes split S2?

A

Inspiration causes a more negative intrathoracic pressure, causing the pulmonary valve to close slower than the aortic valve and splitting the S2 sound

26
Q

What causes an S3 sound?

A

S3 sounds are due to blood flowing against a distended or incompliant ventricle, and suggests that too much blood is flowing into the ventricle

27
Q

What conditions cause an S3 sound?

A

Congestive Heart Failure, Restrictive Cardiomyopathy

28
Q

How can an S3 sound be heard?

A

S3 sounds are heard at the apex with the patient in the LLD position during early diastole (immediately after S2)

29
Q

What causes an S4 sound?

A

S4 sounds are found when atrial contraction forces blood into a stiff ventricle

30
Q

What conditions cause an S4 sound?

A

Left Ventricular Hypertrophy

31
Q

How can an S4 sound be heard?

A

S4 sounds are heard at the apex with the patient in LLD position, low pitch sound during late diastole

32
Q

How are S3 and S4 sounds different?

A

S3 sounds are early diastole immediately after S2 while S4 are late diastole right before S1

33
Q

What characteristics describe a murmur?

A 
Timing (Systole/diastole)
Timing within Systole/diastole (early, mid, late, holo)
Shape (crescendo/decrescendo)
Location of maximal intensity
Radiation of murmur
Intensity rating out of 6
Quality (blowing/harsh)
34
Q

What are the common systolic murmurs?

A

Aortic stenosis and mitral regurgitation

35
Q

Describe aortic stenosis?

A

Systolic murmur
Crescendo-decrescendo
Heard in the aortic area and radiates to the carotid arteries

36
Q

Describe mitral regurgitation?

A

Holosytolic murmur heard best at the apex, radiates to the axilla

37
Q

What sounds should be heard in Diastole?

A

No sound should be heard in diastole; should be totally silent and all murmurs are pathologic

38
Q

What are common diastolic murmurs?

A

Aortic regurgitation and Mitral stenosis

39
Q

Describe Aortic regurgitation?

A

Blowing, decrescendo murmur heard best along the sternal border

Associated with widened pulse pressure

40
Q

What pressure change is Aortic regurgitation associated with?

A

Aortic regurgitation is associated with a widened pulse pressure

41
Q

Describe Mitral regurgitation?

A

Low pitched rumbling diastolic murmur heard at the apex, best heard in the LLD position

42
Q

What should be palpated to obtain a heart rate?

A

Carotid artery, better than radial

43
Q

What pulse contour would be expected with aortic stenosis?

A

Delayed and diminished arterial pulse

44
Q

What pulse contour would be expected with aortic regurgitation?

A

Bounding arterial pulse

45
Q

What pulse contour would be expected with shock?

A

Weak and thready arterial pulse

46
Q

What are the two properties of the JVP and what are they used for?

A

Height of JVP = volume status

Contour of JVP = clues to cardiac disease

47
Q

How is JVP calculated from the angle of Louis?

A

Measure the vertical distance from the angle of Louis to the meniscus of the JVP, then add 5cm

Normal JVP <= 9cm

48
Q

How should an inability to find the JVP be reported?

A

If the JVP cannot be found, report as “JVP not visualized”

Do NOT say “No JVD”, because this implies no distension/elevation

49
Q

Why is a visible JVP in an upright patient automatically a sign that they are fluid overloaded?

A

Normally, the angle of Louis is 5cm from the R. Atrium (which is why we add +5cm to our verticle measure from the angle of Louis)

In an upright patient with visible JVP, the distance of the JVP from the angle of Louis + 5cm is always >= 9cm

50
Q

When does S1 occur on a venous pressure tracing?

A

S1 occurs after the A wave (atrial contraction) and during the C wave (ventricular contraction)

51
Q

What is the X descent?

A

Relaxation of the right atrium

52
Q

What is the V wave?

A

Venous return to the right atrium with a closed tricuspid valve

53
Q

What is the Y descent?

A

Rapid transfer of blood from the Right atrium to the Right ventricle after the tricuspid valve opens

54
Q

What is a thrill?

A

A murmur that can be felt, at least a 4/6

55
Q

When can an S3 sound be normal?

A

During periods of increased cardiac output, such as pregnancy

56
Q

When can an S4 sound be normal?

A

Never

57
Q

What is a murmur?

A

An extra heart sound due to turbulent flow across a vavle

58
Q

Differentiate a murmur and a bruit?

A

A murmur is turbulent flow across a vale while a bruit is turbulent flow across an artery
