Diagrammatic representation of the character of the systolic murmur and of the second heart sound in several abnormalities. The effects of posture, amyl nitrite inhalation, and phenylephrine injection on the intensity of the murmur are shown. (With permission from Barlow, JB. Perspectives on the Mitral Valve. F.A.
