Disclosed herein are new 4-aryl-benzazocine-2,6-diones of Formula I ##STR1## in which R.sup.1 is phenyl, naphthyl or phenyl or naphthyl substituted by one to three moieties selected from fluoro, chloro, bromo, and alkyl or alkoxy of 1 to 4 carbon atoms; R.sup.2 is --R.sup.3 --NR.sup.4 R.sup.5, wherein R.sup.3, R.sup.4 and R.sup.5 are, independently, straight or branched chain alkyl groups of 1 to 4 carbon atoms or R.sup.4 and R.sup.5 are concatenated to form nitrogen ring having 3 to 8 carbon atoms; and X and Y are, independently, hydrogen, alkyl or alkoxy of 1 to 4 carbon atoms, dialkylamino or dialkyl-carboxamido wherein each alkyl group has 1 to 4 carbon atoms, cyano, alkylacyl of 1 to 4 carbon atoms, fluoro, chloro, nitro, dialkylsulfonamido wherein each alkyl group has 1 to 4 carbon atoms, or alkylsulfonyl of 1 to 4 carbon atoms, or a pharmaceutically acceptable salt thereof. The compounds of Formula I are useful as anti-arrhythmic agents.
