We have investigated the regulation of intracellular free calcium in heart muscle using the free acid form of the Ca2+ indicator fura-2 iontophoretically microinjected into rat cardiac trabeculae or ferret papillary muscles. This method shows great promise in elucidating a number of crucial questions in cardiac excitation-contraction coupling.
