This study reports a rare case of bundle branch re-entrant tachycardia presenting with both left and right bundle branch block morphologies in a patient with a non-dilated left ventricle, expanding understanding of this ventricular tachycardia variant.
Area of Science:
- Cardiology
- Electrophysiology
- Cardiac Arrhythmias
Background:
- Bundle branch re-entrant (BBR) tachycardia is an uncommon ventricular tachycardia (VT).
- It typically affects patients with structural heart disease and conduction system impairment.
- BBR tachycardia usually presents with either left bundle branch block (LBBB) or right bundle branch block (RBBB) QRS morphology.
