Q

Effect of abrupt standing

A

Most murmurs diminish in intensity due to reduced venous return and subsequently reduced R/L ventricular diastolic volumes
Murmur of HCM becomes louder

Q

Effect of squatting

A

Most murmurs become louder (also with passive leg raising)

Murmur of HCM becomes softer

17
Q

Effect of valsalva maneuver

A

Most murmurs decrease in intensity

Murmur of HCM becomes louder

18
Q

Effect of sustained hand grip

A

Most useful in differentiating AS from MR
AS = decreased intensity
MR = increased intensity

19
Q

Respiration physiology

A

Venous return to RV increases during inspiration resulting in increased volume
Venous return to LV decreases during inspiration resulting in decreased volume
Primarily alters intensity of murmurs that originate from right side of heart

20
Q

Abrupt standing physiology

A

Decreases venous return to heart = decreases RV and LV diastolic volumes and SVs
Can lead to a fall in arterial pressure and a reflex increase in HR

21
Q

Valsalva maneuver physiology phase 1

A

Onset = transient increase in LV output

22
Q

Valsalva maneuver physiology phase 2

A

Straining = decrease in venous return, RV and LV volumes, SVs, MAP, and PP
Associated with reflex increase HR

23
Q

Valsalva maneuver physiology phase 3

A

Release = further reduction in LV volume

24
Q

Valsalva maneuver physiology phase 4

A

Increase in stroke volume and arterial pressure

Reflex slowing of HR (overshoot)

25
Q

Which phase of valsalva is most useful and practical for differentiating heart sounds?

A

Phase 2 = straining

26
Q

Hand grip physiology

A

Increase in systemic vascular resistance, arterial pressure, CO, and LV volume/filling pressure

27
Q

Expiration

A

Increases return to left heart

28
Q

Effect of inspiration on TR?

A

Enhanced (increased RA return)

29
Q

Effect of squatting and hand grip on MR?

A

Enhanced (increased TPR)

30
Q

Effect of hand grip on VSD?

A

Enhanced (increased afterload)

31
Q

Effect of midsystolic click in MVP with maneuvers that decrease venous return (standing, Valsalva)?

A

Decreased volume = occurs EARLIER

32
Q

Effect of midsystolic click in MVP with maneuvers that increase venous return (squatting)?

A

Increased volume = occurs LATER

33
Q

Effect of hand grip on AR?

A

Increased intensity

34
Q

Effect of vasodilators on AR?

A

Decreased intensity

35
Q

Effect of expiration on MS?

A

Enhanced (increased LA return)
