Association between dissociated firing in isolated pulmonary veins and the initiation and maintenance of atrial fibrillation

摘要

Background Whether dissociated firing (DiFi) in isolated pulmonary veins (PVs) implies arrhythmogenicity of the particular PV and, therefore, a better outcome of PV isolation (PVI) for paroxysmal atrial fibrillation (PAF) is debated.
