Left Ventricular End Diastolic Volume and Ejection Fraction Calculation: Correlation between Three Echocardiographic Methods

Figure 1

LVEF (a) and EDV (b) values according to the method used. Box-plot representation showing the distribution of LVEF values according to the method which was used. The inbox line represents the mid value. The inbox circle represents the mean value. The edges of the box represent the 25th and 75th percentiles (Q1 and Q3), and the ends of the whiskers represent the upper and lower adjacent values, which are the most extreme values within Q3 + 1.5  (Q3 − Q1) and Q1 − 1.5  (Q3 − Q1), respectively. At first sight, 3DE values seem to be the lowest. Box-plot representation showing the distribution of EDV values according to the method which was used. At first sight, STE values seem to be the lowest.
