Hemodynamic Effects of Strontium in the Dog

  • William H. Barry
  • Donald C. Harrison


The divalent cation of strontium, Sr2+, has been shown to be capable of substituting for Ca2+ in maintaining excitability of certain nerve and muscle membranes (1,2); in electromechanical coupling in an alga (3); and in excitation-contraction coupling in both skeletal and cardiac muscle (4). Also, in some isolated cardiac muscle preparations it has been shown to have potent positive inotropic effects (5–7).
