[Effect of stress of "struggle" and the stress of "capitulation" on the resistance of the myocardium to excessive level of calcium].
The resistance of isolated, perfused by Langendorf the heart was compared in the experiments on Wistar rats with elevated by 7.3 times the concentration of the calcium in perfused solution. It was shown that one-hour stress of the "struggle" raised but six-hour one decreased the resistance of the heart to arrhythmogenic and contraction action of the surplus Ca2+.
