在动物实验中,烟酰胺可增强窦房结功能,促进房室传导,抗快速型实验性心律失常,并有正性肌力作用。临床研究表明,烟酰胺可明显改善病窦综合征和房室传导阻滞的临床表现,为上述疾病的治疗提供了新的且可能有效的途径。 In animal experiments, niacinamide can enhance sinus node function, promote atrioventricular conduction, anti-rapid experimental arrhythmia, and positive inotropic effect. Clinical studies have shown that nicotinamide can significantly improve the clinical manifestations of sick sinus syndrome and atrioventricular block, providing a new and potentially effective approach to the treatment of these diseases.
