WebbSimpson’s Rule Formula: Let us suppose we are given the definite integral as follows: \int\limits_a^b {f\left ( x \right)dx} Now, if we want to get the suitable approach of the above integral, we need to make partition of the interval [a, b] into subintervals of even numbers n. The width of each subinterval is given by: WebbThe recommended method for EF calculation is the Simpson's or modified Simpson's method (38) using apical four-chamber and apical two-chamber views ( Figure 3).

It can refer to the cardiac atrium, ventricle, gall bladder, or leg veins, although if unspecified it usually refers to the left ventricle of the heart.
