Flashcards in Murmurs Deck (22):
0

Holo systolic
High pitched blowing murmur
Systolic
Loudest at apex and radiates to the axilla

Mitral regurgitation - enhanced by increased systemic resistance and increased return to LA (expiration)

1

Continuous machine-like murmur
Loudest at S2
Best heard at left infraclavicular area

PDA -often due to congenital rubella

2

What murmurs are enhanced by decreased venous return?

HOCM
MVP

3

What maneuvers decrease venous return?

Valsalva
Standing

4

What maneuvers increase systemic resistance?

Hand grip

5

What murmurs decrease with increased preload?

HOCM
MVP

6

What maneuvers increase preload?

Squatting
Passive leg raise

7

Best heard over apex
Mid systolic click
Late systolic crescendo

MVP - seen in Marian's, myxomatous change

8

High pitched blowing murmur
Diastolic decrescendo

Aortic regurgitation - enhanced by hand grip

9

What decreases intensity of aortic regurgitation?

Vasodilators

10

What are the buzz words for aortic regurgitation?

Wide pulse pressure
Bounding pulses
Pulsating nails bed
Head bobbing

11

Opening snap
Late diastolic rumble

Mitral stenosis - usually due to chronic RF

12

Crescendo-decrescendo systolic
Ejection click
Radiates to carotids/heart base

Aortic stenosis - caused by age, bicuspid aortic valve

13

What are the sx of aortic stenosis?

Syncope
Angina
Dyspnea in exertion
Paradoxical splitting

14

Holo systolic
Harsh
Loudest at tricuspid area (left eternal border)

VSD

15

Radiates to neck, clavicle, shoulder
Harsh
Heard at left sternal border

Aortic stenosis

16

What are the 2 hold systolic murmurs?

VSD, mitral regurgitation, tricuspid regurgitation

17

What 2 murmurs have decrescendo?

Aortic stenosis and aortic regurgitation

18

Which murmurs have ejection clicks?

MVP and aortic stenosis

19

Radiates to right sternal border
Enhanced by inspiration
Holo systolic high pitched blowing murmur

Tricuspid regurgitation

20

What is a split S2 that does not change with respiration indicate?

Fixed splitting seen in ASD.
This is a left to right shunt that causes increased right atrial and right ventricular volumes therefore causing the pulmonic valve to close later since there is more flowing through it.

21

What is paradoxical splitting?

When the LV doesn't empty fast enough
Seen in aortic stenosis and left bundle branch block.
Paradoxical because aortic valve closes after the pulmonic which is not normal.
