[Effect of electric cardiac stimulation in experimental supraventricular tachycardia].

Abstract

Experimental supraventricular tachyarrhythmia was produced in dogs by the local application of aconitine on the left auricle. The effect of various types of stimulations (right auricular, right ventricular, double-delayed right auricular and right ventricular-right auricular double-delayed stimulation) was studied for the suppression of supra-ventricular (overdrive) tachyarrhythmia. It was found that the electric stimulation of the heart is an effective method of suppressing tachyarrhythmias, though there is a significant difference in the anti-arrhythmic effects of the electric stimulations of various types. For suppression of the supraventricular tachyarrhythmia caused by aconitine, delayed double-right auricular stimulation seemed to be the most effective with respect to the right ventricle. The bioelectric features of aconitine arrhythmia and the mechanism of the antiarrhythmic effect of the electric stimulation of the heart are discussed.
