Figure 10 Relationship Between Augmentation of Flow and Pressure Waves in the Carotid Artery
Relationship between augmentation of simultaneously recorded flow (ordinate) and pressure (abscissa) waves in the carotid artery of 56 normal subjects age 20 to 72 years (R = 0.913, p < 0.0001). Lowest values of augmentation were seen in younger and highest values in older individuals. Inset is method used for calculating flow and pressure augmentation as late systolic augmentation ÷ pulse height (54).
