Transfer of coupling of premature ventricular contractions to an ectopic ventricular tachycardia: a mechanism for atypical bidirectional tachycardia.

Abstract：

:Bidirectional tachycardia was observed on Holter tracings recorded from a dog three days after the production of a small freeze lesion on the wall of the left ventricle. A bigeminal rhythm with fixed coupling of ventricular premature contractions was interrupted by a burst of ventricular tachycardia of different morphology. The ventricular premature contractions, originally coupled to the sinus beats, became coupled to the new ventricular tachycardia with an identical coupling interval. This resulted in a dibirectional tachycardia, created by the "transfer" of coupling of premature ventricular contractions to a separate ectopic ventricular tachycardia.
