title: [The effect of a crown-ether derivative, ethmozine and etatsizin on the functioning of the calcium pools in the guinea pig myocardium].
abstract: Analysis of the component structure of single contractions of papillary muscles in guinea pigs was used to study the effects of the crown ether derivative benzylase-15-crown-5 and the antiarrhythmic agents ethmozine and ethacizine. The negative inotropic effect of these compounds was shown to be associated with limited penetration of calcium ions from the sarcolemmal pool into cardiac cellular myoplasm.
