Summary
Becker muscular dystrophy can cause wide complex tachycardia due to bundle branch reentry. Radiofrequency catheter ablation offers a curative treatment for this ventricular arrhythmia in affected patients.
Area of Science:
- Cardiology
- Genetics
- Neurology
Background:
- Becker muscular dystrophy is a genetic myopathy.
- Ventricular arrhythmias are a known complication.
Observation:
- A patient with Becker muscular dystrophy presented with recurrent wide complex tachycardia.
- Electrophysiologic testing was performed.
Findings:
- The tachycardia mechanism was identified as bundle branch reentry.
- This is a specific type of ventricular tachycardia.
Implications:
- Consider bundle branch reentry in Becker muscular dystrophy patients with ventricular arrhythmias.
- Radiofrequency catheter ablation is a potential curative therapy.
