Key Points

Radiofrequency catheter ablation effectively targets discrete origins of polymorphic PVCs, enhancing arrhythmia management.
Key findings indicate that the earliest PVC potentials correlate with His recordings, revealing potential ablation sites.
Analysis focused on arrhythmia arising from fasciculoventricular fibers and direct His-septal connections for safer interventions.
The results may enable refined ablation techniques and improved outcomes for patients with complex PVC patterns.

Implication

Observational analysis shows arrhythmia arises from discrete targets in His septum, indicating effective ablation strategies.
