The Purkinje system can be a source of arrhythmias and has been shown to trigger ventricular fibrillation. The complexity of the molecular mechanisms of ventricular fibrillation, and the incomplete understanding of Purkinje arrhythmogenicity, make the identification of vulnerable individuals challenging. In this Review, Haissaguerre and colleagues discuss the current knowledge of the pathophysiological mechanisms underlying Purkinje-related arrhythmias, and highlight the current therapeutic options.
