[Electrocardiographic examination of the crew of the 2d "Saliut-4" expedition].
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 changes in the myocardium should not be, however, ruled out.
