Hypoxia increases potassium efflux from mammalian myocardium.
Hypoxia with or without simultaneous depletion of extracellular glucose increases 42K-efflux in cat and guinea-pig papillary muscles and bovine Purkinje fibres. The change observed in K efflux may be the result of an increase in K conductance at rest.
