Bundle branch reentry: a possible mechanism of ventricular tachycardia.
Electrophysiologic studies were performed in three patients suffering from attacks of paroxysmal tachycardia with wide QRS complexes. Two patients had atrioventricular dissociation. The arrhythmia could be initiated and terminated by premature ventricular stimulation in all three patients. One patient developed the arrhythmia after rapid atrial stimulation. In each subject, the QRS complexes du...

متن کاملBundle Branch Reentrant Ventricular Tachycardia
Bundle branch reentrant (BBR) tachycardia is an uncommon form of ventricular tachycardia (VT) incorporating both bundle branches into the reentry circuit. The arrhythmia is usually seen in patients with an acquired heart disease and significant conduction system impairment, although patients with structurally normal heart have been described. Surface ECG in sinus rhythm (SR) characteristically ...
متن کاملTranscatheter electrical ablation of right bundle branch. A method of treating macroreentrant ventricular tachycardia attributed to bundle branch reentry.
The present study describes the clinical and electrophysiological characteristics of sustained bundle branch reentrant ventricular tachycardia treated with electrical ablation of the right bundle branch. Seven patients presented with syncopal episodes, and six of the seven had documented episodes of ventricular tachycardia. All patients had depressed left ventricular ejection fraction with card...
متن کاملBundle branch reentrant ventricular tachycardia after transcatheter aortic valve replacement
Introduction Bundle branch reentrant ventricular tachycardia (BBR-VT) is a well-described entity that accounts for 6% of inducible sustained monomorphic VT during electrophysiology studies. BBR-VT is a macroreentrant VT involving the HisPurkinje system and usually requires some form of conduction delay in the His-Purkinje axis. BBR-VT is commonly seen in patients with nonischemic dilated cardio...
