Pyrimidinedione derivatives of the formula: ##STR1## wherein R.sup.1 and R.sup.2 is so linked with each other as to make an alkylene chain and thus form a heterocyclic structure, A, R.sup.3, R.sup.4, X.sup.1, X.sup.2 and X.sup.3 are substituents, respectively, and n is 2 or 3 have a basic backbone in which a phenyl group part and a pyrimidinedione part are linked by a structure comprising an alkyl chain and a heterocyclic ring having two nitrogen atoms. These compounds are useful for a medical treatment of cardiac arrhythmias.
Pyrimidinedione衍生物的化学式为:##STR1## 其中R.sup.1和R.sup.2通过一个烷基链相连,从而形成一个杂环结构,A,R.sup.3,R.sup.4,X.sup.1,X.sup.2和X.sup.3分别是取代基,n为2或3,具有一个基本骨架,其中苯基部分和嘧啶二酮部分通过一个包含一个烷基链和一个含有两个氮原子的杂环环的结构相连。这些化合物对于治疗心律失常很有用。
