Increased SR load in MCT cells is reversed by BB. A SR Ca2+ content was estimated during steady state pacing at 5 Hz by rapid application of caffeine (indicated by arrow) to deplete SR stores. B SR load was increased in MCT compared to CON, and returned to normal levels by BB. Myocyte numbers given in fig. N = 5–6 rats per group, one way ANOVA. *P < .05.
