[Conservative therapy of supraventricular tachycardias]

The conservative management of supraventricular tachycardias is briefly surveyed and described. For exact treatment a description of different ways of origin of tachycardias such as focal activity or reentry-mechanisms is given. A diagram at the end shows the site of influence of different antiarrhythmic drugs in the atria and the AV-node as well as the accessory pathways in preexcitation. A list of antiarrhythmics according to their classification of Vaughan Williams and of Tournboul completes this survey.
