Fluctuations in intracellular calcium concentration and their effect on tonic tension in canine cardiac Purkinje fibres.

Ca2+-activated aequorin luminescence and tension were measured in dog Purkinje fibres during twitches and during the increase in resting force produced by exposure of the fibres to a low-Na+ solution after 3 min without external K+. Over the restricted range which could be examined, the relation bet...
