Figure 32-15 Distal pulse wave amplification of the arterial pressure waveform. When compared with pressure in the aortic arch, the more peripherally recorded femoral artery pressure waveform demonstrates a wider pulse pressure (compare 1 and 2), a delayed upstroke (3), a delayed, slurred dicrotic notch (compare short arrows), and a more prominent diastolic wave.
