[Gestosis: predictive value of clinoorthostatic test with ECG].
OBJECTIVE
To examine value of the clinoorthostatic test (COT) with ECG conducted in pregnancy trimesters I, II and III for prediction of gestosis.


METHODS
The trial included 66 healthy gravidae aged 18-26 years (mean age 19.1 +/- 2.84 years) and 135 gravidae with extragenital pathology aged 17-43 years (mean age 25.1 +/- 0.78 years) on pregnancy trimester I, II and III. Within the observation period the gravidae underwent 3-4 COT with ECG. Arterial pressure and ECG were registered in dorsal and erect positions on minute 1, 3 and 10 on pregnancy week 9-12, 16-18, 26-28.


RESULTS
Most of the gravidae who subsequently developed gestosis on trimester I exhibited cardiovascular maladaptation recordable at COT with ECG. Comparison of COT results with pregnancy outcomes gave grounds for establishment of 12 prognostic tests predicting gestosis with probability 75-100% in the tests sensitivity at least 80%, specificity 89%.


CONCLUSIONS
COT with ECG is a simple, available and informative method of predicting gestosis and can be used by obstetricians for detection of gestosis risk groups among the gravidae.
