Exaggerated Reactivity of Parasympathetic Nerves Is Involved in Ventricular Fibrillation in J-Wave Syndrome.
Brugada syndrome (BrS) and early repolarization syndrome (ERS) are termed the J-wave syndrome. In most cases of J-wave syndrome, ventricular fibrillation (VF) often occurs around midnight or in the early morning when parasympathetic tone is augmented. ⋯ Our results suggest that exaggerated reactivity of parasympathetic nerves, as represented by increased BRS, may underlie VF in patients with J-wave syndrome.
