[Evaluation of cardiac output in pathological arteriovenous blood shunt].

The paper is concerned with the development of quantitative determination by thermodilution of cardiac output and abnormal arteriovenous blood shunt in patients with congenital heart diseases. A method for graphic analysis of the curves on the basis of revealed standard ratios of the descending part heights is proposed. It allows one to obtain the values of left-right shunts similar to those attainable by the method of Fick.
