Procainamide Facilitated Induction of Purkinje Premature Ventricular Contractions in Patient with Idiopathic Ventricular Fibrillation
Idiopathic ventricular fibrillation secondary to short coupled PVCs (Sc-PVCs) can be challenging to diagnose and treat given the need to exclude other forms of heart disease. In addition, the presentation of ventricular fibrillation often leads to a focus on stabilizing the patient followed by investigation into the potential explanations for the VF event. Short coupled PVCs can be a target for ablation when found to trigger VF. They often arise from the Purkinje system and often have periods of relative quiescence.
