WebJun 10, 2024 · Recall that LVEDP is the pressure at the end of left ventricular diastole. On a normal EKG, this corresponds to the peak of the QRS complex. Graphically superimposing the EKG over the LV waveform, you can draw a line straight down from the point on the EKG to the LV waveform. Where it falls on the waveform is the calculated LVEDP. WebCurrently, two-dimensional (2D) echocardiography for calculation of ejection fraction is the dominant method for assessing left ventricular function (systolic function). It should be noted, however, that three-dimensional (3D) echocardiography offers greater precision in the calculation of ejection fraction, and 3D measurements will presumably ...
