Abstract
In the preceding chapters the importance of both Ca current and SR Ca release in E-C coupling have been discussed and it was suggested that Ca from both sources could contribute to the activation of contraction. A major goal of this chapter is to clarify how these two sources of Ca may differ in particular cardiac muscle preparations and under different experimental situations. I will also discuss how the transsarcolemmal Ca fluxes and the SR Ca fluxes interact in a simple framework of overall Ca regulation in cardiac muscle.
