Radiofrequency Catheter Ablation of Polymorphic Premature Ventricular Contractions

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.
