Heart Rate Variability and Cardiovascular Reflex Tests for Assessment of Autonomic Functions in Preeclampsia

Figure 4

Comparison of spectral components of heart rate variability in normalised units in 3 groups of subjects; PE, preeclampsia; NP, normotensive pregnant; NN, normal nonpregnant. (a) LF, low frequency power and (b) HF, high frequency power. Values are mean ± SD (n=40). p < 0.05 versus normal nonpregnant females; p < 0.05 versus normotensive pregnant females.
