Bundle branch reentry vt

WebIntroduction: Bundle branch reentry is an uncommon mechanism for ventricular tachycardia. More infrequently, both fascicles of the left bundle may provide the substrate for such macroreentrant bundle branch circuits, so-called interfascicular reentry. The effect of adenosine on bundle branch reentrant mechanisms of tachycardia is unknown. WebApr 6, 2024 · However, the intrafascicular re-entry has not been demonstrated at the right Purkinje system level yet. Bundle branch re-entry VTs are often observed in patients with acquired heart disease, which might involve the His-Purkinje system, and, therefore, would lead to slow conduction within the Purkinje system necessary for the occurrence of re-entry.
