[Dependence of the cardiac pumping function on arterial resistance in lung cancer and in the stages of its surgical treatment].

The relationship between the arterial resistance and pumping function of the heart was studied in 203 patients by the method of integral rheography. An inverse relationship between the pumping capacity of the heart and vascular resistance was confirmed at different stages of examination and treatment of the patients. The maximal levels of increase of the minute blood flow volume were established as well as the conditions under which the increase of the cardiac output discontinued despite the decrease of the postexercise.
