Gaussian Modelling Characteristics of Peripheral Arterial Pulse: Difference between Measurements from the Three Trimesters of Healthy Pregnancy

Figure 3

Gaussian modelling characteristics of the radial pulse measured at the three trimesters of healthy pregnant women. Their means ± SDs are given. (a–c) show peak amplitude changes of the first, second, and third Gaussian waves (H₁, H₂, H₃) at the three trimesters; (d–f) show changes of peak time position of the first, second, and third Gaussian waves (N₁, N₂, N₃) at the three trimesters; (g–i) shows changes of half-width of the first, second, and third Gaussian waves (W₁, W₂, W₃) at the three trimesters. ∗∗ represents .
