New compounds of the formula (I) where X is
straight-chained alkylene, or -S- wherein R1 is hydrogen, aryl, or lower alkyl; W is hydrogen, hydroxy, amino,
, 0-alkyl, alkylsulfonamide or O-aralkyl; (Y)A is positioned ortho to W and is an aminoalkyl having the formula -CH2NR2R3, wherein R2 and R3 are the same or different and may be hydrogen, lower alkyl, hydroxyalkyl, cycloalkyl, alkoxyalkyl, alkoxyaryl, aryl, heteroaryl, or R2 and R3 may together with N form a 5 to 7 membered heterocyclic group optionally including oxygen, nitrogen, or sulfur as a second hetero-atom, and A is 1 or 2; N and M are independently from O to about 5; and Ar is a substituted or unsubstituted pyridine optionally fused with one or more heteroaryls and pharmaceutically acceptable salts of such compounds are useful in the treatment of various cardiac arrhythmias.
