[Prevention of stress-induced disorders of myocardial Na, K-ATPase activity using adaptation to short-term stress].
It was shown that adaptation to short-term emotional-painful stresses prevented both the decline in the activity and the increase in thermal denaturation rate of Na,K-ATPase in sarcolemmal vesicles isolated from the rat myocardium exposed to prolonged stress. The role of Na-pump damage in the disturbance of the electrical stability of the heart and the development of stress-induced arrhythmia is discussed.
