Electrophysiological characteristics of Purkinje potentials and the conduction system in premature ventricular contractions triggering ventricular fibrillation after myocardial infarction
Purkinje potentials show distinct properties that influence both QRS duration and PVC timing. The presence of preceding Purkinje potentials together with QRS duration may help guide ablation strategies. In rare cases, Purkinje activity conducts retrogradely from the left bundle and anterogradely through the RB, modifying PVC morphology.
