Vagal Tone: How Important Is It in Triggering Atrial Fibrillation?

The parasympathetic nervous system modulates the electrophysiological properties of most structures involved in normal cardiac function and in experimental and human arrhythmias. However in vivo it is actually difficult to evaluate the pure vagal effect since sympatho-vagal interactions are specifically involved in modulating the electrophysiological parameters. The not universally accepted concept of dividing the atrial fibrillation episodes in vagal and sympathetic induced ones is mainly based on anecdotal cases and on clinical preselected models.
