title: [Action potentials and ionic currents].
abstract: Our knowledge of the ionic currents underlying the cardiac action potential has much increased in recent years. Principally three membrane current components are characterised, of which the change carries are sodium ions, calcium ions and potassium ions. Different drugs influence the current components in various ways. For an extensive description of the ionic currents in the heart, the bibliography is given.
