Substituted 1-oxo-1,2-dihydroisoquinolinoylguanidines and 1,1-dioxo-2H-1,2-benzothiazinoylguanidines, a process for their preparation, their use as medicament or diagnostic agent, and also a medicament containing them. Acylguanidines I ( I ) Image with X equal to carbonyl or sulfonyl; R(1) equal to H, (cyclo)alkyl, phenyl; R(2) equal to H, alkyl, and their pharmaceutically suitable salts, are described. They are obtained by reacting a compound II (II) Image with guanidine. The compounds have no unwanted salidiuretic but very good antiarrhythmic properties. They are able, as a consequence of inhibition of the cellular Na+/H+ exchange mechanism, to be used for the treatment of all acute or chronic ischemia-induced damage.
