Abstract:
:We describe a patient with bundle branch reentry ventricular tachycardia with 1:1 VA conduction in whom resetting was performed while obtaining simultaneous recordings from the right ventricular apex (V) and His-bundle electrogram. Both the tachycardia return cycle and the V-His interval demonstrated an increasing reset response, while the His-V interval demonstrated a flat reset response. These reset responses are consistent with a partially excitable gap localizing to the V-His portion of the bundle branch reentry circuit.
