Webb9 okt. 2024 · ventricular " has been described elsewhere [10]. Left ventricular ejection fraction was calculated by the biplane Simpson’s method in a semi-automated fashion with manual correction and was classiﬁed as decreased (<40%), mildly decreased (40–50%), and normal (>50%) for all subjects evaluated [18]. Webb6 sep. 2024 · Ejection fraction = (EDV – ESV)/EDV EDV: End diastolic volume; ESV: End systolic volume. The difference between the two gives the stroke volume. Ejection fraction is in fact the stroke volume divided by the end diastolic volume. In other modalities of imaging also, the same principle is applied.
