right

negative intrathoracic pressure increases venous return to the RA
What does the hand-grip maneuver do in terms of pressures?
increases systemic vascular resistance
What does the Valsalva maneuver do in terms of cardiac filling?
reduces venous return to heart
What does the Valsalva maneuver do to most heart murmurs?
makes them quieter
What does the Valsalva maneuver do to preload and afterload?
Decreases preload
Increases afterload
Which heart murmurs get louder w/ the Valsalva maneuver?
mitral prolapse and hypertrophic cardiomyopathy
What maneuver makes the murmurs of hypertrophic cardiomyopathy and mitral prolapse softer?
squatting

increases both
