A new mapping and ablation strategy for premature ventricular complexes originating from the proximal left anterior fascicle under the guidance of electrocardiographic characteristics
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.
