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

Figure 1

Comparison of (a) SDNN and (b) RMSSD values in 3 groups of subjects; PE, preeclampsia; NP, normotensive pregnant; NN, normal nonpregnant; SDNN, standard deviation of normal R-R intervals; RMSSD, square root of mean squared differences of successive R-R intervals. Values are mean ± SD (n=40). p < 0.05 versus normal nonpregnant females; p < 0.05 versus normotensive pregnant females.
