[Myocardial reaction and lung ventilation response to inhalation of the gaseous hypoxic mixture GGS-10 in patients with rheumatoid arthritis].

: The initial and end parts of the ventricular complex of the ECG and the roentgenopneumopolygraphy data were assayed in 22 patients with rheumatoid arthritis before and after inhalation of the gaseous hypoxic mixture (GGS-10) consisting of 90% of nitrogen and 10% of oxygen. After the inhalation of the mixture the area of the ST-T segment significantly increased as compared with the initial data, mainly in the AVR, V2 and V5 leads of the ECG. In addition, individual features of the changes in respiratory pulmonary function were discovered, which directly correlated with the disease stage.
