Acetamide derivatives are provided having the structure ##STR1## wherein X is a single bond, --CH.sub.2 -- or --O--, R.sup.1 and R.sup.2 may be the same or different and are lower alkyl, phenyl-lower alkoxy-lower alkyl, lower alkenyl, phenyl-lower alkyl or lower alkoxy, or ##STR2## may be taken together to form a 5- to 7-membered heterocyclic ring optionally containing one other hetero atom, such as nitrogen, sulfur or oxygen; Y is hydroxyl, OR wherein R is lower alkyl, lower alkenyl or lower alkanoyl, or ##STR3## wherein R.sup.1 and R.sup.2, and R.sup.1 and R.sup.2 taken together with the nitrogen to which they are attached are as defined above, and n is 1 to 6. These compounds are useful as anti-arrhythmia agents and have been found to be effective in the treatment of acute myocardial infarction.
