Abstract |
Diethylamine analogue of ethmozine (DAA ethmozine) administered intravenously in the doses of 0.5-1 mg/kg exerts marked antiarrhythmic effect both experimentally and clinically, slight effect on the arterial pressure and myocardial contractility and led to insignificant and to statistically insignificant depression of automatism of the sinus node and on the fibres of the conductive system. DAA ethmozine enhanced the duration of the refractory periods of atriae and of the atrio-ventricular node by 20-30%, increased the time of stimulation conduction at all the levels of the conductive system of the heart. Sensitivity of the rapid sodium channels to DAA ethmozine exceeded by one order their sensitivity to ethmozine proper. The sum total of the results and also the preliminary data on the high antiarrhythmic activity of DAA ethmozine justifies the conclusion that this drug may prove to be effective in the treatment of cardiac arrhythmias.
