Impact of Na+ concentration change in extracellular fluid on normalized INa I/V curve of cardiomyocytes. When the NaCl concentration in the extracellular fluid decreases from 140 to 105 mM, 82 mM, 70 mM and 35 mM, the normalized INa I/V curve changes as shown in the figure. The peak values of 82 mM, 70 mM and 35 mM NaCl groups were compared with the control group, P < 0.0001.
