Compounds of the formula ##STR1## wherein A is --CH.sub.2 --CH.sub.2 --, --CH.dbd.CH--, --NH--CO--, --CH.sub.2 --CO-- or ##STR2## where R.sub.7 is alkyl of 1 to 3 carbon atoms, and B is methylene, carbonyl or thiocarbonyl, or A is --CO--CO--, --N.dbd.CH--, ##STR3## where R.sub.8 is hydrogen or alkyl of 1 to 3 carbon atoms substituted by a phenyl, methoxyphenyl or dimethoxyphenyl, and B is methylene; E is n-alkylene of 2 to 4 carbon atoms optionally substituted by an alkyl of 1 to 3 carbon atoms, 2-hydroxy-n-propylene, 2-hydroxy-n-butylene or 3-hydroxy-n-butylene; G is n-alkylene of 1 to 5 carbon atoms optionally substituted by an alkyl of 1 to 3 carbon atoms, wherein one methylene group of an n-alkylene of 2 to 5 carbon atoms can be replaced by a carbonyl group, with the proviso that B represents a methylene or carbonyl group, or methylene-n-hydroxy-alkylene of 1 to 4 carbon atoms, where the methylene group is attached to the nitrogen atom; and R.sub.1 to R.sub.5 are simple substituents of various types; and non-toxic, pharmacologically acceptable acid addition salts thereof. The compounds as well as their salts are useful as bradycardiacs.
