WebThe bulge is referred to as the dicrotic notch. This signifies the closure of the aortic valve at the end of systole. The peaks average the systolic pressure. The troughs average the diastolic pressure. …. The v-wave stands alone between two slopes, and it represents right atrial filling pressure during diastole. WebJan 5, 2024 · (a) Pulmonary artery catheter entering the pulmonary artery, balloon inflated. (b) The pulmonary artery waveform is distinguished from the right ventricular waveform by an overall increase in diastolic pressure and a dicrotic notch (representing closure of the pulmonic valve)
