ejection murmur

a type of systolic murmur occurring predominantly in midsystole, at the time of maximal ejection volume and blood flow velocity, such as that heard in aortic or pulmonary stenosis; it is due to ejection of blood into the root of the aorta or pulmonary artery, is diamond-shaped, and ends before the second heart sound. Cf. regurgitant m.
