[Optimization of the use of etmozin in treating patients suffering from frequent ventricular extrasystole].

Fifteen patients with frequent and stably recordable ventricular premature heart beat received etmozine treatment (the priming dose 500 mg, the maintenance dose 200 mg). Of these, 3 patients presented with coronary heart disease, 1 with mitral valve prolapse, and 11 with the idiopathic pattern of heart rhythm disorders. The drug was found to be highly effective. The 90% decrease in the number of ventricular premature heart beats during 2 h after administration of the priming dose can be used as criterion in predicting the efficacy of etmozine treatment.
