ABSTRACT
Most idiopathic premature ventricular contractions (PVCs) originate from the right outflow tract, and catheter ablation is an established treatment option.1 In contrast, PVCs originating left ventricle (LV) can be difficult to treat with ablation. Idiopathic LV are frequently associated conduction systems, such as Purkinje fiber network, have been reported form a unique complex arrhythmic substrate.2
