Excitation-contraction coupling in cardiac Purkinje fibers. Effects of caffeine on the intracellular [Ca2+] transient, membrane currents, and contraction
The effects of caffeine on tension, membrane potential, membrane currents, and intracellular [Ca2+], measured as the light emitted by the Ca2+-activated photoprotein aequorin, were studied in canine cardiac Purkinje fibers. An initial, transient, positive inotropic effect of caffeine was accompanied...
