Key result
Purkinje potential-guided RF ablation effectively treats idiopathic left anterior fascicular tachycardia.
Why the study?
Idiopathic ventricular tachycardia with right bundle branch block configuration and right-axis deviation may originate from the left anterior fascicle, but optimal ablation guidance is unclear.
Population
A 45-year-old man with idiopathic VT with right bundle branch block and right-axis deviation
Comparison
Radiofrequency catheter ablation guided by presumed Purkinje potential vs endocardial ventricular activation and pace mapping

May support Purkinje-guided ablation in fascicular VT; hypothesis-generating and requires prospective validation.
Case Report (n=1)
In idiopathic VT with RBBB and right-axis deviation, targeting a presumed Purkinje potential may be more effective for guiding ablation than endocardial activation or pace mapping.
Bogun et al. (1995) conducted a case report in Idiopathic ventricular tachycardia (n=1). Radiofrequency catheter ablation guided by a presumed Purkinje potential was evaluated on Successful ablation of VT. Radiofrequency catheter ablation guided by a presumed Purkinje potential was effective for treating idiopathic left anterior fascicular tachycardia.
