Pulmonary capillary wedge pressure is a phase-delayed, amplitude-damped version of LA pressure. During diastole with a nonstenotic mitral valve, the pulmonary venous system, LA, and LV is a continuous circuit and the PCWP is then reflective of the LV diastolic pressure. 20 The level of PCWP is ... 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. takuache silverado
