The method based on impedance cardiography for evaluation of blood pressure in pulmonary artery is presented. This method was tested by using data of 109 patients with various cardiac and pulmonary diseases, and for all of them two-dimentional transtoracal cardioechoscopy was performed in aim to confirm or exclude pulmonary artery hypertension. Comparison of results received by applying both methods for measurement the blood pressure in pulmonary artery showed the especially significant correlation of data - Spearman’s coefficient of correlation r=0,836, p=0,0001. These results permit to assume, that impedance cardiography, as non-invasive, inexpensive and user-friendliness method could be used for blood pressure evaluation in aim to detect the hypertension of pulmonary artery.
