Additional evidence for re-entry within the bundle branches in man.
Abstract
A repetitive, non-paced ventricular beat (V3) often occurs during ventricular extrastimulus testing at short coupling intervals when critical retrograde His-Purkinje conduction delay is achieved. Though re-entry within the bundle branches has been proposed as the mechanism for V3, it has been difficult to exclude local re-entry. In the present case, we consistently recorded a right bundle branch potential as well as a bundle of His potential before each V3. The anterograde activation sequence of these potentials provides evidence against local re-entry and supports re-entry involving the bundle branches as the mechanism for V3.
