Typical and reverse-typical bundle branch re-entrant ventricular
tachycardia in the absence of structural heart disease
Abstract
Introduction: BBRVT is a type of ventricular tachycardia that
occurs when there is a re-entrant circuit involving the His-Purkinje
system and the bundle branches. The condition is characterized by a
rapid heart rate (200–300 beats/min), and can lead to symptoms such as
palpitations, dizziness, and syncope. BBRVT is often associated with
underlying structural heart disease, such as cardiomyopathy, but can
also occur in individuals with structurally normal hearts. We present a
case of a 20-year-old male with exercise-induced palpitations and
syncope, who was found to have sustained VT due bundle re-entrant
tachycardia in the absence of overt structural heart disease.
