Web22 mar. 2015 · For an ejection fraction in the range of 50% to 55%, most of the commonly used tests, if carefully performed, are accurate within a few percentage points (e.g. 55% plus or minus 3%). With respect to the lower limit of “normal” LVEF, it is important to remember that even at rest, the LV pumps a slightly different amount of blood in every beat. WebThe left atrium is dilated and hypocontractile. Despite the presence of impaired left ventricular relaxation, the markedly elevated left atrial pressure results in a high velocity of early diastolic filling, which stops abruptly because of an abnormally rapid rise in ventricular pressure and atrial dysfunction.
