Abstract
Abstract N-(Arylthioalkyl)-N'-(aminoalkyl)ureas and thioureas and oxidation derivatives having the formula ##STR1## wherein B is thio, sulfinyl or sulfonyl; R 1 and R 2 are hydrogen, loweralkyl, cycloalkyl, 2-furanyl, phenyl, substituted phenyl or phenyl-loweralkyl and R 3 and R 4 are hydrogen, loweralkyl, phenyl or phenyl-loweralkyl wherein phenyl is optionally substituted, or R 3 and R 4 taken with the adjacent nitrogen form a heterocyclic residue. The compounds are useful in the treatment of cardiac arrhythmia.
