Web4. Dicrotic notch (reflective wave) during diastole Grade A: Normal Sharp systolic peak with prominent dicrotic notch Grade B: Mildly Abnormal Sharp peak, absent dicrotic notch; downslope is bowed away from baseline Abnormal PVR waveforms The PVR waveform shape changes with the level of PAD proximal to the ankle. These include: WebD. Right ventricle Rationale: right ventricle (clue: obvious notch on the left side of the waveform) Clues that will assist in determining an RV waveform are: - the wave will look taller in appearance than a PA waveform - an RV waveform is symmetrical in shape; there is no dicrotic notch seen on the right side (downslope) of the waveform - the right … popcorn malen
