    Abstract: There are described benzoylguanidines of the formula I where R(1) is H, Hal, -NO2, -C IDENTICAL N, Xo-(CH2)p-(CF2)q-CF3, R(5)- SOm, R(6)-CO- or R(6)R(7)NO-SO2-, where X is O, S, NR(14), m is 0-2, o is 0, 1, p is 0-2, q is 0-6, R(5) and R(6) are alk(en)yl, -CnH2n-R(8), CF3, n is 0-4, R(8) is cycloalkyl, phenyl, R(6) also being H, R(2) is where Y is O, -S- or -NR(12)-; R(11), R(12) = H, alkyl, and h is zero or 1, and i, j and k are 0-4, but where h, i and k are not simultaneously zero, R(3) is defined as R(1), or is alkyl, -X-R(13) where X is O, S, NR(14), R(14) is H, alkyl, R(13) is H, (cyclo)alkyl, -CbH2b-R(15) where b is 0-4, R(15) is phenyl, R(4) is H, -OR(16) or -NR(16)R(17) where R(16), R(17) are H, alkyl and their pharmaceutically tolerable salts. They are obtained from a compound II by reaction with guanidine, in which R(1) to R(4) have the meaning indicated and L is a leaving group which can be easily nucleophilically substituted. The compounds are outstandingly suitable as antiarrhythmic medicaments having a cardioprotective component for infarct prophylaxis and infarct treatment and also for the treatment of angina pectoris, where they also preventively inhibit or severely decrease the pathophysiological processes in the formation of ischaemically induced damage, in particular in the elicitation of ischaemically induced cardiac arrhythmias.
