Sodium-potassium balance is maintained by the sodium potassium pump.
钠钾泵维持钠钾平衡。

Enter calcium, which, by inhibiting the activity of the sodiumpump, regulates signal firing, and may conserve energy and keep the high-frequency cells from burning out.
加入钙离子，可以抑制钠泵的活动，调节信号的产生，可以保存能量，保护高频细胞。

Digoxin directly inhibits the sodium-potassium ATPase pump in the membrane of the cardiac myocyte, causing an increase in intracellular sodium and calcium which increases myocardial contractility.
