This invention encompasses anthranilamides with heteroarylsulfonyl side chain, process for their preparation, their use as medicament or diagnostic aid, and pharmaceutical preparations containing them. Compounds of formula I, 1 in which R1 to R7 have the meanings stated in the claims, act on the Kv1.5 potassium channel and inhibit a potassium current which is referred to as the ultra-rapidly activating delayed rectifier in the atrium of the human heart. They are therefore suitable as novel antiarrhythmic ingredients, such as for the treatment and prophylaxis of atrial arrhythmias, e.g. atrial fibrillation (AF) or atrial flutter.
