Q

IJV vs carotid pulse

A

venous pulse: biphasic, varies with position (angle of recline), height falls on inspiration, non-palpable/collapsible, abdominal pressure displaces pulse upward
-carotid pulse: single sharp wave, palpable/non-compressible

Q

observing neck veins

A

look at IJV (better than EJV)

  • find meniscus: for normal patients, angle of recline is 30-45 degrees
  • for patients with increased CVP, angle of recline is increased
  • for patients with decreased CVP, angle of recline is decreased

21
Q

Features of mitral regurg

23

  • palpable S4
24
Q

areas of auscultation for heart sounds

A
  • Aortic: R 2nd ICS, parasternal line
  • Pulmonic: L 2nd ICS, parasternal
  • Erb’s point: L 3rd ICS, parasternal (left ventciular outflow)
  • Tricuspid: L 4th-5th ICS, parasternal
  • M: L 5th ICS, MCL
25
Q

sequence of valve closure

A

MTAP (mitral–>tricuspid–>aortic–>pulmonic)

26
Q

auscultation S1

A
  • caused by closure of AV valves
  • best heard at apex
  • clinical variable is intensity:
  • inc. intensity when inc. thickness of AV valve (mitral stenosis 2/2 rheumatic fever), inc. separation b/t AV leaflets at onset of ventricular sysole (MS, or shortened PR interval)
27
Q

auscultation S2

A
  • due to closure of semilunar valves (pulmonic and aortic)
  • best heard at base
  • clinical parameter: splitting
  • physiologic splitting: occurs on inspiration (delayed P2 and early A2); should only be heard over pulmonic area
  • paradoxical splitting: occurs on expiration (delayed A2, A2 follows P2); due to aortic stenosis, hypertension, LV dysfx (MI, L bundle branch block)
  • fixed splitting: occurs in both inspiration and expiration due to ASD
28
Q

S2 splitting heard at apex

A

pulmonary hypertension

29
Q

tambour S2

A

loud and ringing S2 due to dilatation of aortic root (marfan’s syphilitic aortitis)

30
Q

mid-late systolic clicks

A

assoc. with MVP, most common congenital valvular disease

31
Q

auscultation S3

A
  • low pitched, soft early diastolic sound
  • best heard with bell at apex in LLD position
  • caused by rapid deceleration of blood against ventricular wall=vol-overloaded states
  • young atheletes with bradycardia (physiologic S3)
  • mitral regurg
  • tricuspid regurg
  • LV failure (presents with tachycardia=S3 gallop)
32
Q

auscultation S4

A
  • low pitched, soft, late-diastolic extra sound
  • best heard with bell at apex with patient in LLD position
  • caused by strong atrial contraction due to ventricular hypertrophy (stiff ventricle) which occurs in pressure overloaded states–aortic stenosis, hypertension, pulmonary hypertension
  • S4 over tricuspid area: strong R atrial contraction, strong A wave in neck veins
  • S4 over mitral area: strong L atrial contraction
  • with tachycardia=S4 gallop
33
Q

murmur

A

extra heart sound produced by turbulent blood flow through heart chambers
-can occur in systole or diastole but not both

34
Q

bruit

A

turbulent blood flow through an arteyr

most common causes: PDA, AV fistula

35
Q

Hum

A

turbulent blood flow through a vein

36
Q

diastolic murmur + systolic ejection flow murmur

A

severe aortic regurg

37
Q

systolic murmur and diastolic S3

A

severe mitral regurg

38
Q

murmur of mitral regurgitation

A

Causes:

  • dilatation of annulus fibrosus (heart failure)
  • acquired mitral valve damage (rheumatic fever)
  • MVP (mid-late systolic click)
  • dysfunction papillary muscle (ischemia)
  • rupture of chordae tendinae (infection)

Murmur: systolic

  • loudest at apex
  • plateau-shaped
  • starts immediately after S1 and extends all the way to S2 (holosystolic)
  • can radiate to L. axilla
  • assoc. w/ palpable S3 in severe cases
39
Q

murmur of aortic stenosis

A

valvular type most common

causes:

  • congenital (bicuspid valve); pts <50
  • degenerative/calcific valve disease (most common cause in US, elderly)
  • rheumatic fever (most common cause worldwide)

murmur: systolic
- diamond shaped (crescendo-decrescendo)
- starts immediately after S1 and ends before S2
- can radiate to neck
- palpable S4 if severe

Gallavardin phenomenon: can be mistaken for mitral regurg when listening at apex (mitral area)

40
Q

how to differentiate mitral regurg and aortic stenosis?

A

hand grip maneuver (inc. afterload)

  • mumur of MR is enhanced
  • murmur of AS is softened
41
Q

murmur of aortic regurgitation

A

Causes:

  • aortic valve damage (calcific aortic degeneration, rheumatic fever, congenital defect, infective endocarditis, trauma)
  • aortic root dilatation (marfan’s syndomre, syphilis, degerative, aortic dissection)
  • VSD

Murmur: diastolic

  • best heard at Erb’s point (L. 3rd ICS parasternal line); patient sitting upright and leaning forward with held exhalation
  • diastolic tapering murmur
  • if sever can have systolic ejection flow murmur
42
Q

strain valsalva or standing from squatting

A

dec. venous return:
MVP: inc. intensity murmur (moves earlier in systole and lengthens(
HOCM: inc. intensity murmur
AS: dec. intensity

43
Q
