We describe a 66-year-old woman who had an alternating bundle branch block consisting of coexisting occurrence of right bundle branch block (RBBB) and left bundle branch block (LBBB) combined with Mobitz type II atrioventricular block (AVB). A prolonged PQ interval was associated with the RBBB pattern whereas it was not apparent in the LBBB pattern. Electrophysiologic study revealed that the LB...
Re-entry within the His-Purkinje system (HPS) was consistently observed in 15/24 consecutive patients in whom retrograde refractory period studies were performed using His bundle electrograms and the ventricular extrastimulus method. Within a narrow range of ventricular coupling intervals (V,V2), V, retrogradely conducted to the bundle of His (H2) with significant infra-His bundle conduction de...
BACKGROUND Definitive diagnosis of bilateral bundle-branch delay/block may be made when catheter-induced right bundle-branch block (RBBB) develops in patients with baseline left bundle-branch (LBB) block. We hypothesized that a RBBB pattern with absent S waves in leads I and aVL will identify bilateral bundle-branch delay/block. METHODS AND RESULTS Fifty patients developing transient RBBB pat...
V ENTRICULAR extrasystoles can occur anywhere in the cardiac cycle. When they occur toward the end of diastole they may be synchronous with the next conducted impulse resulting in a fusion complex. We report a case of left bundle-branch block associated with end-diastolic ventricular extra-systoles that occur in bigeminal rhythm; this results in fusion complexes that apparently normalize the bu...
