WebPulmonary artery diastolic pressure can be estimated by looking at the pulmonary regurgitation signal (parasternal short-axis view). The velocity at end-diastole (at the QRS complex on the ECG) is converted into a pressure gradient (modified Bernoulli equation). The estimate of right atrial pressure is added to this value. sPAP= PRvel2 x 4 + RAP WebFeb 15, 2016 · The evaluation parameters included lumen diameter (LD), peak systolic velocity (PSV), and end-diastolic velocity (EDV) and were measured at the C5–6 intertransverse segment of the vertebral artery.
