N-[(disubstituted amino)alkyl]-3,4 (or 4,5)-diaryl-1H-pyrazole-1-acetamides and pyrazole-1-propanamides, useful for treating cardiac arrhythmias in mammals, are prepared by reacting a lower-alkyl ester of pyrazole-1-acetic or propanoic acid with an appropriate diamine or by reacting a lower-alkyl ester of a pyrazole-1-acetic or propanoic acid with an .omega.-aminoalkanol, followed by activation of the alcohol and displacement by an appropriate amine.
