Abstract

PIMENTA, J., ET AL.: Return Ventricular Rhythm: New Mechanism for Tachyarrhythmia. A case study is presented in which the electrocardiographic patterns during tachycardia showed ventricular premature depolarizations with retrograde conduction to the atria probably using a left-sided anomalous pathway and reentry to the ventricles with normal ventricular activation and duplication of the heart rate. This type of tachycardia is being labeled “return ventricular rhythm” and, as far as it is known, this is the first description of its mechanism.
