[Various aspects of individualization of drug therapy of extrasystole]

The clinical experience of drug therapy of 673 patients with extrasystole of different genesis has demonstrated that the nature of the underlying pathology and the topical characteristics of the extrasystole produce a comparatively moderate effect upon the antiarrhythmic action of Novocainamide, Chinidine, Obsidan, Isoptine, Bellataminal. Of certain importance in this context is the determination of the degree of prematurity of the extrasystole, their stability, as well as the periodic structure of the sinus rhythm as shown by the rhythmogram.
