The result of prompt squatting is an increase of the venous return and of the arterial resistance. Consequences are increasing of the end-diastolic and systolic chamber pressure, stroke volume, average arterial blood pressure as well as decreasing of the frequency of the pulse controlled by baro-receptors. The regulatory mechanism both change the intensity of heart murmurs of various cardiopathies and of functional heart murmurs in children. Only the systolic murmur of muscular subvalvular aortic stenosis softens. The experiment is most valuable for the recognition of mild insufficiency of semilunar valves.
