Abstract

In cardiac cells, sodium-calcium exchange is important in regulation of intracellular calcium concentration as a primary mechanism of calcium extrusion. Earm et al., [1, 2] recorded the inward current after short depolarizing pulses, and showed the inward current was a Na-Ca exchange current activated by intracellular calcium released from the sarcoplasmic reticulum (SR) and contributed to the generation of the late plateau phase of the action potential in rabbit atrial myocytes. Furthermore, by using fluorescence Ca indicator measurements, Lipp & Pott [3, 4] showed clearly that the inward current was activated by Ca release from the SR and is exclusively carried by a Na-Ca exchange mechanism.
