Abstrakt: Adaptation of rats to repcated short-term stress exposure prevents, to a considerable extent, contractural and arrhythmogenic effects of high concentrations of extracellular Ca on isolated heart. Increased efficiency of SR Ca-pump functioning and a significant increase in Ca pump resistance to autolysis are proved to play the main role in this effect. [ABSTRACT FROM AUTHOR]
