Title: [Ventricular tachycardia caused by bundle branch reentry]. Author: Gallay P. Journal: Arch Mal Coeur Vaiss; 1992 Dec; 85 Spec No 4():77-83. PubMed ID: 1307197. Abstract: Ventricular tachycardia by bundle branch reentry is a special type of ventricular tachycardia. A rare arrhythmia, it occurs in very particular conditions of ventricular dilatation and conduction defects. The diagnosis is based on electrophysiological findings associating a His potential preceding the ventriculogramme with a HV interval comparable to that observed in sinus rhythm, and spontaneous variations of the cycle length between two ventriculogrammes preceded by those of the His potentials. Contrary to what is observed in other forms of ventricular tachycardia, pacing is possible from the atrium without changes of the QRS complexes and the presence of fusion complexes excludes the diagnosis. Treatment consists of radiofrequency ablation of the right bundle branch.[Abstract] [Full Text] [Related] [New Search]
