FIELD: medical equipment. ^ SUBSTANCE: fetus is subject to echo-cardiograph test. Time of isovolumetric relaxation (IRT) of left ventricle is measured as well as heart beat rate (beats per minute). Calculative value of IRT is found from relation of IRT=0,54A1-0,032A2+33,8, where A1 is period of pregnancy, weeks; A2 is heart beat rating, beats per minute. If measured value of IRT is 10% higher than calculated value for fetus, then arterial hypertension is diagnosed. If measured value of IRT is 10% lower than calculated one, then absence of hypertension is testified. ^ EFFECT: ability of revealing of changes in central and peripheral dynamics of fetus at early period of pregnancy. ^ 3 ex |
