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.

| ejection fraction |
The ejection fraction (EF) or, more correctly, left-ventricular ejection fraction (often abbreviated LVEF) is a measure of how much blood the left ventricle of the heart pumps out with each contraction. The normal left ventricle has an average volume of 100ml and with each heart beat ejects approximately 70 ml, the stroke volume. ...
