Abstract: Amino-substituted benzenesulphonylureas and -thioureas of the formula I <IMAGE>  are described. The compounds I are used for treating cardiac dysrhythmias and for preventing sudden heart death due to arrhythmias and can therefore be used as antiarrhythmics. They are particularly suitable for cases in which arrhythmias are the consequence of a constriction of a coronary vessel, such as in angina pectoris or acute myocardial infarct.
