Since the cardiac activity during atrial fibrillation (AF) may be influenced by autonomic modulations, in this study, a novel method to quantify the effects of the most common anesthetic agent (propofol) in AF ablation procedures is introduced. This study has two main objectives: first, to assess whether the sedation earlier to radio frequency ablation(More)
The effect of conventional i.v. anaesthetic agents on atrial fibrillation (AF) dynamics has not been fully addressed. We aim to evaluate whether the most frequently used intravenous anaesthetic agent, propofol, modifies AF organization parameters. Multiple and simultaneous intraatrial bipolar recordings from 27 patients in AF were analyzed before and after(More)
The mechanisms responsible for the maintenance of atrial fibrillation (AF) are not completely understood yet. It has been demonstrated that AF can be modulated by several cardiac diseases, the autonomic nervous system and even drugs with purportedly no antiarrhythmic properties. We evaluated the effects of a widely used anaesthetic agent (propofol) in the(More)
The mechanisms responsible for the initiation, maintenance and spontaneous termination of atrial fibrillation (AF) are not yet completely understood. Though much of the underlying physiology has been well determined, it has been demonstrated in numerous clinical investigations that the autonomic nervous system plays an important role in AF genesis and(More)
