Figure 6 Pressure Waveforms in Arm and Aorta of Young, Middle-Aged, and Old Subjects
Pressure waveforms measured in the radial artery (top) and synthesized for the ascending aorta (bottom) in 3 women of the same family—an 18-year-old at left, a 48-year-old at center, and a 97-year-old at right. Pulse pressure is increased almost 4-fold in the ascending aorta and 2-fold in the upper limb (4). Time calibration = 0.5 s.
