This report demonstrates a previously undescribed mechanism of His-Purkinje reentry (reentry within the right bundle branch) in humans.
Answers are grounded in this paper and cite their sources.
Novel right bundle reentry shown in one case; leaves open its prevalence and clinical relevance in His-Purkinje tachycardias.
Reentry within the right bundle branch which, to our knowledge is a hitherto undescribed mechanism of His-Purkinje reentry in man, was elicited during programmed right ventricular stimulation. Electrophysiologic analysis excluded atrioventricular nodal reentry. His bundle reentry, reentry involving both bundle branches, and intraventricular micro-reentry.
