Research output: Contribution to journalArticlepeer-review


Inferences on the effects of sympathetic and vagal activities in favouring the occurrence of paroxysmal atrial fibrillation have been mainly based on the observed changes in heart rate before the arrhythmic event. Recently, spectral analysis of heart rate variability, by providing indices of sympathetic and vagal modulation of heart period, has furnished important information on the alteration of neural regulatory mechanisms in different clinical conditions. We therefore employed this approach to evaluate the presence of alterations in sympatho-vagal balance before the onset of two episodes of atrial fibrillation in a patient with no evidence of organic heart disease.
