Excitation-contraction coupling in cardiac Purkinje fibers. Effects of cardiotonic steroids on the intracellular [Ca2+] transient, membrane potential, and contraction
The [Ca2+]-activated photoprotein aequorin was used to measure [Ca2+] in canine cardiac Purkinje fibers during the positive inotropic and toxic effects of ouabain, strophanthidin, and acetylstrophanthidin. The positive inotropic effect of these substances was associated with increases in the two com...
