The effect of high K+/low Na+-Tyrode's solution on Ca2+ uptake into neonatal rat atrium was studied using 45Ca2+. Substitution of 60-129 mM Na+ in Tyrode's solution by equimolar concentrations of K+ or choline, significantly (with the exception of 60 mM choline substitution) increased Ca2+ uptake above control. Furthermore, the Ca2+ uptake stimulated by K… CONTINUE READING
