Becker muscular dystrophy with bundle branch reentry ventricular tachycardia.
ABSTRACT This report describes a case of Becker muscular dystrophy presenting with recurrent symptomatic wide complex tachycardia. Electrophysiologic testing demonstrated the mechanism to be bundle branch reentry ventricular tachycardia. It is important to consider this potential mechanism in patients with ventricular arrhythmias who have this particular clinical entity, since radiofrequency catheter ablation can represent a curative treatment.

ABSTRACT: Electrical conduction heart system following the atrio-ventricular node is constituted by the His bundle and its branches, as well as their distal division localized in the subendocardial layer which forms the Purkinje network. These structures play a role in the initiation and/ or maintenance of various arrhythmias. The simplest ones are isolated premature beats, the most dangerous ones are polymorphic ventricular tachycardia, ventricular fibrillation or electrical storms. Clinical presentation and the existence of a heart disease are crucial for correct diagnosis and treatment. Therapeutic options are medical treatment, catheter ablation and device implantation. Extreme cases may require urgent ablation, and their correct diagnosis may be life saving.Archives of Cardiovascular Diseases Supplements 12/2011; 3(3):195–206.
