A new mapping and ablation strategy for premature ventricular complexes originating from the proximal left anterior fascicle under the guidance of electrocardiographic characteristics
- study
- consecutive patients
- prospectively mapped and ablated
Authors' conclusion
Under the guidance of electrocardiographic characteristics, this new mapping and ablation strategy (from the RCC alone) is a simple, safe, and effective method for elimination of proximal LAF-PVCs.
