WebPulmonary Artery (PA) Pressure Waveform: Notice the similarity between the pulmonary artery pressure waveform and the arterial pressure waveform. Systole begins during the sharp upstroke from the trough. Diastole begins at the dicrotic notch on the backside of the waveform. This is an arterial waveform, but it is for the pulmonary artery. WebA right ventricle waveform will appear taller than the previous pulmonary artery tracing (if measured on the same scale). The systolic pressure of a right ventricular tracing will be the same as the pulmonary artery pressure, but the diastolic right ventricle pressure will be lower than the pulmonary artery diastolic.
