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. Web25 aug. 2009 · Visual assessment of left ventricular ejection fraction (LVEF) is often used in clinical routine despite general recommendations to use quantitative biplane Simpsons (BPS) measurements. Even thou quantitative methods are well validated and from many reasons preferable, the feasibility of visual assessment (eyeballing) is superior. There is …
