Echocardiographic views - Film n° 3

This is the same view as in film 2. By coupling the two-dimensional mode with the motion mode, it is possible among other things to measure the dimensions of the left ventricle (end-diastolic, end-systolic diameters) and to deduce the fractional contraction of the diameter. From the formula V = D³ or Teicholz's formula [V = 7D³/(2.4 + D)], the measurement of diameters can be used to calculate the volume of the left ventricle. The two-dimensional mode/motion mode coupling is used to visualize a paradoxical septal movement and to localize it in the cardiac cycle
