RESUMO
Aim To study the effect of [P-(1-Benzotriazole methl)-Benylacrylic acid sodium,abbreviated for BMBS] on experimental arrhythmias. Methods Arrhythmias models induced by drugs in animals were used to observe the effect of BMBS on experimental arrhythmias. Results BMBS 25,12.5 mg?kg -1 iv markedly increased the dose of aconitine for inducing Ventricular premature beats (VP), ventricular tachycardia (VT) and ventricular fibrillation (VF) in rats, as well as that of ouabain for inducing VP, VT, VF and cardiac arrest (CA) in guinea pigs. Also, it postponed the onset time and shortened the duration of arrhythmias induced by barium chloride in rats and decreased the number of animals showing biphasic arrhythmias. Conclusion BMBS has significant effect on experimental arrhythmias.
