It is important to understand the mechanism by which LDVF is maintained and defibrillated. Purkinje fibers (PFs) have been demonstrated to play a key role in the onset of certain types of ventricular fibrillation. In this review, we discuss the electrophysiological difference between PFs and working myocardium, and the role of the PFs in the maintenance and termination of LDVF.展开更多
