Explain what happens to right-sided murmurs with inspiration. Right-sided murmurs generally increase in intensity with inspiration Inspiration causes a decrease in intrathroacic pressure allowing air to enter the lungs. This decrease in intrathoracic pressure allso causes an increase in the venous blood return to the right side of the heart.

How is pseudonormal diastolic filling patterns altered with a Valsalva maneuver? Reduction in venous return during Valsalva maneuver results in an overall decrease of LV filling velocities without significant change in the E/A ratio in normal. Decrease in venous return does change in pseudonormal because atrial empting is abnormal. Due to reduced emptying in early diastole, emptying with atrial contraction will atrial increase
