Impact of Na⁺ concentration change in extracellular fluid on the adsorbed Ca²⁺ and Na⁺ of cardiomyocytes surface. In the Ca²⁺ adsorption experiment, the number of Ca²⁺ adsorbed was compared with the number of Na⁺ desorbed (a). The number of Ca²⁺ was adsorbed (b). In the Na⁺ adsorption experiment, the number of Na⁺ adsorbed was compared with the number of Ca²⁺ desorbed (c). The number of Ca²⁺ was desorption (d). (E-1, E-2 and E-3 were 105 mM NaCl group, 70 mM NaCl group and 35 mM NaCl group). *P < 0.05, comparison of rightward circulation among the three groups.
