Die Wirkung von Adrenalin auf das Ruhepotential von Myokardfasern des Vorhofs

Summary Dog auricle fibres were impaled by 2 intracellular electrodes. The first electrode measured the effect of adrenaline on the resting potential, and through the second one electrotonic impulses were applied.Adrenaline increases the resting potential by 1–35 mV. The polarisation is higher at a low resting potential and increases with the dose.Small polarisations were not accompanied by a detectable change of the membrane resistance. During higher polarisations, the membrane resistance was reduced to 50%.
