During the first month of the orbital flight the cosmonauts showed an increase in the blood pressure and filling in the jugular veins whereas during the second month they exhibited a decrease in these parameters below the preflight level. Throughout the mission the pressure in the pulmonary artery remained slightly increased. The time of contractions of the(More)
In the Salyut-5 flight studies of circulatory functions were continued. Heart rate, arterial pressure, time intervals of the left and right ventricles were measured at rest. Peripheral resistance and cardiac output were calculated. At early flight stages cardiovascular changes occurred due to an increased blood inflow to the heart. During the second half of(More)
The inflight electrocardiograms in 12 leads of the cosmonauts P.I. Klimuk and V.I. Sevastyanov showed a trend towards a decrease of the atrio-ventricular and an increase of the intraventricular conduction as well as a decrease of the T voltage. These changes seemed to be adaptive and developed as a result of the positional changes of the heart. Metabolic(More)
The authors have shown that the color decoding of x-ray-radioisotope information on 50 lung cancer patients (150 radiograms and 80 scannograms) raised the diagnostic efficacy. It opens up opportunities for the objective quantitative processing of results by performing histographic analysis of similar optical density zones. These data are impossible to(More)
In Salyut-5 crewmembers, electrocardiograms were recorded in 12 standard and D--S leads. No marked changes in bioelectric properties of the myocardium were detected. However, during the second part of the mission B. V. Bolynov and V. M. Zholobov showed changes in the terminal portion of the ventricular complex in the left sternal leads. It is presumed that(More)
