  • Title: [The current concepts of the effect of cardiac glycosides on sinus node function and atrioventricular conductivity].
    Author: Bobrov VA, Shchepotin IuB.
    Journal: Ter Arkh; 1991; 63(9):142-4. PubMed ID: 1759209.
    Abstract:
    The clinical aspects of the influence of cardiac glycosides on the sinus node and atrioventricular junction in health and dysfunction are reviewed. It has been shown that digitalis drugs do not produce any effect on sinus node automatism including that in dysfunction. Cardiac glycosides suppress enhanced atrioventricular conduction and do not affect it provided it remains within normal. The mechanisms by which cardiac glycosides may act are discussed: extracardiac, cholinomimetic (in the acute test and direct one) and influencing heart conduction components (when used continuously).
