N-(3,5-bis-disubstituted aminomethyl-4-hydroxy)benzyl aromatic sulfonamides and N-(3,5-bis-disubstituted aminomethyl-4-hydroxy)phenyl aromatic sulfonamides compounds in accordance with the animal test, are active in the prevention and the treatment of cardiac arrhythmia. These compounds are prepared as corresponding diamines by the condensation of optionally substituted aromatic sulfochlorides with p-hydroxybenzylamine, p-aminophenol, or the like, which followed by the Mannich reaction of the resulted corresponding aromatic sulfamides with formaldehyde and secondary amines; or directly obtained by the reaction of the aromatic sulfamides with 4-amino-2,6-bis-disubstituted aminomethylphenol. Subsequently, the diamines are reacted with various acids to provide their salts.
