  • Title: [Calcium-regulating hormones and functional activity of the myocardium during beta-adrenoreceptor block by inderal].
    Author: Barabanova VV, Egorov VIa.
    Journal: Fiziol Zh SSSR Im I M Sechenova; 1985 Dec; 71(12):1579-86. PubMed ID: 4092777.
    Abstract:
    Effect of calcitonin (CT) upon the AP of contractile cardiomyocytes was absent under conditions of blockade of beta-adrenoreceptors with inderal which reduced the level of intracellular sodium and ionized calcium. Inderal facilitated the effect of parathyroid hormone on the myocardium electrical activity. In conditions of blockade of beta-adrenoreceptors, the CT acted upon the autorhythmic activity of pace-maker cardiomyocytes as in control solution.
