- a.It decreases ventricular filling
- b.It increases the murmur of aortic insufficiency
- c.It decreases the murmur of mitral regurgitation
- d.It decreases the murmur of ventricular septal defect
- e.It has the opposite effect of passive leg raising
- f.It has the same effect as amyl nitrite
The answer is : (b).
Squatting like passive legraising are act to increase ventricular filling. Therefore, they increase blood flow through the heart and increase the murmurs of ech of following : aortic insufficiency, ventricular septal defect, and mitral regurgitation. The hypotensive inhalation agent amyl nitrite decreases the murmurs of AI, VSD, and MR.
