Murmurs Flashcards
1
Q
Bedside maneuver: inspiration
A
- increases intensity of right heart sounds
2
Q
Bedside maneuver: expiration
A
- increases intensity of left heart sounds
3
Q
Bedside maneuver: hand grip (increased systemic vascular resistance)
A
- increases intensity of MR, AR, VSD, MVP
- decreases intensity of AS, hypertrophic cardiomyopathy murmurs
4
Q
Bedside maneuver: valsalva (decreased venous return)
A
- decreases intensity of most murmurs
- increases intensity of MVP, hypertrophic cardiomyopathy murmurs
5
Q
Bedside maneuver: rapid squatting (increased venous return, increased preload, increased afterload with prolonged squatting)
A
- decreases intensity of MVP, hypertrophic cardiomyopathy murmurs
6
Q
Description of MR
A
- holosystolic, high-pitched “blowing murmur” that radiates towards axilla
- systolic murmur
7
Q
Maneuvers that can increase intensity of MR
A
- increased TPR (squatting) or LA return (expiration)
8
Q
Description of TR
A
- holosystolic, high pitched murmur that radiates towards right sternal border
- systolic murmur
9
Q
Maneuvers that can increase intensity of TR
A
- increased RA return (inspiration)
10
Q
Description of AS
A
- crescendo-decrescendo systolic murmur following ejection click
- radiates towards carotids/heart base
- systolic murmur
11
Q
Description of VSD
A
- holosystolic, harsh-sounding murmur
12
Q
Maneuvers that increase VSD
A
- hand grip due to increased afterload
- systolic murmur
13
Q
Description of MVP
A
- late systolic crescendo murmur with midsystolic click
14
Q
Maneuvers that increase MVP
A
- decreased venous return (standing or Valsalva)
- systolic murmur
15
Q
Description of AR
A
- high pitched “blowing” decrescendo murmur
- bounding pulses, and head bobbing
- diastolic murmur
