Three-dimensional pulse diagram. (a) Simulated three-dimensional pulse diagram. (b) Variation of the APV in a pulse period. 1, Radial artery vasoconstriction and increased point amplitude. 2, Expansive change in the middle when the average amplitude of 12 points reached its maximum. 3, Radial artery vasodilation and decreased point amplitude. 4, Funnel-like variation in the middle when the average amplitude of 12 points reached its minimum.
