Table 2

Cardiovascular reflex tests in different groups.

TestParametersPreeclamptic females
pregnant females
Normal non pregnant females

Test for sympathetic component

Lying to standing testAverage fall in systolic blood pressure (mmHg)3.00 ± 3.965.1 ± 6.411.75 ± 2.78

Tests for parasympathetic component

Lying to standing test30:15 ratio1.13 ± 0.111.22 ± 0.111.40 ± 0.17
Deep breathing testChange in heart rate (bpm)13.48 ± 6.1222.6 ± 8.1819.82 ± 5.97
Expiration:Inspiration ratio1.19 ± 0.101.34 ± 0.121.37 ± 0.13

Values are expressed as mean ± standard deviation; n, number of subjects; 30:15 ratio, immediate heart rate response to standing; p < 0.05 versus normal non pregnant females; < 0.05 versus normotensive pregnant females.
