New benzopyran derivatives of general formula (I) in which: R.sub.1 represents a hydrogen or halogen atom or a hydroxy, alkyloxy, nitro, amino, alkylsulphonamido or acylamino radical, R represents (1) radical ##STR1## R.sub.2 and R.sub.3, which may be identical or different, being H, halogen, OH, alkyl, alkyloxy, NH.sub.2, alkylsulphonamido or NO.sub.2, or (2) a radical ##STR2## n being 0 or 1, R.sub.4 being H, alkyl or optionally substituted phenyl and Q is acyl, alkylsulphonyl or ##STR3## Y being --CO-- or --SO.sub.2 -- and Z being a single bond, --CH.sub.2 -- or --NH--, or (3) a radical ##STR4## n being 0 or 1, m being 0 or 2, X being C or N (if n=0), W being a bond or --NH-- and AR being pyridyl, indolyl, quinolyl, 2-alkylquinolyl or phenyl optionally substituted with R.sub.2 and R.sub.3, provided that n=0 when X equals N, or (4) a radical of general formula: ##STR5## R.sub.7 being H or alkyl, or alternatively (5) a radical ##STR6## R' and R" are identical and represent hydrogen atoms or alkyl radicals, their isomeric forms and the mixtures thereof, and their addition salts with acids. These new products are useful as anti-arrhythmic and antifibrillating agents. ##STR7##
