title: [Effects of ethmozine on ventricular fibrillation threshold in acute occlusion of the coronary artery in dogs].
abstract: In experiments on dogs with acute left descending coronary artery occlusion, ethmozine (3 mg/kg) was tested for effects on the threshold of ventricular fibrillation occurring as a result of high-frequency electric stimulation. Two hours after occlusion, the fibrillation threshold became significantly lower than the control values. Ethmozine used in this period enhanced the ventricular fibrillation threshold in some experiments and diminished it in the others. Four hours following the occlusion, the fibrillation threshold did not differ from the control ones. Ethmozine given in this period caused a significant increase in the ventricular fibrillation threshold. It was concluded that 4 hours after the onset of experimental myocardial infarction are the minimal time period following which administration of ethmozine failed to decrease electric stability of the heart.
