Novel ethenylphenol indoles of the formula <IMAGE> I wherein R and R1 are individually selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms, cycloalkyl of 3 to 7 carbon atoms, cycloalkylalkyl of 4 to 7 carbon atoms and aralkyl of 7 to 12 carbon atoms optionally substituted with 1 to 3 members of the group consisting of halogen, methyl, ethyl, methoxy, ethoxy, methylthio, -CF3, -NH2 and -NO2 or R and R1 together with the nitrogen atom form an optionally unsaturated heterocycle optionally containing a second heteroatom selected from the group consisting of -O-, -S- and <IMAGE> R' is hydrogen or alkyl of 1 to 5 carbon atoms, a together with X is =0 and b is hydrogen or a together with b is a carbon-carbon bond and X is hydrogen, the dotted line indicates the possibility of a double bond with the compounds having the trans configuration if a double bond, A is selected from the group consisting of <IMAGE> and -(CH2)n-, n is 2,3,4 or 5, R2 is selected from the group consisting of hydrogen and alkyl of 1 to 5 carbon atoms with the proviso that R and R1 are not both hydrogen when A is <IMAGE> and their non-toxic, pharmaceutically acceptable acid addition salts having anti-arrhythmic and anti hypertensive properties and the property of blocking slow calcium-sodium channels and novel intermediates.
