Very Prolonged Episode of Self-Terminating Ventricular Fibrillation in a Patient With Brugada Syndrome


      We report the case of a very prolonged spontaneous episode of self-terminating ventricular fibrillation in a patient with Brugada syndrome (BrS). The patient first underwent implantation of an internal loop recorder after an episode of prolonged loss of consciousness (several minutes) that was suggestive of a nonarrhythmic cause. After a second episode of prolonged syncope, subsequent interrogation of the loop recorder revealed a very prolonged episode of self-terminating ventricular arrhythmia, lasting 2 minutes and 41 seconds. This short report emphasizes the fact that an arrhythmic cause of syncope should not be ruled out in patients with BrS presenting with very prolonged loss of consciousness.


      Nous rapportons le cas d’un épisode très prolongé de fibrillation ventriculaire spontanément résolutive chez un patient atteint du syndrome de Brugada (SBr). Le patient était porteur d'un holter implantable suite à un épisode de perte de connaissance prolongée (plusieurs minutes) qui était évocatrice d'une cause non rythmique. Après un deuxième épisode de syncope prolongée, l’interrogation des mémoires du holter implantable a révélé un épisode très prolongé d’arythmie ventriculaire spontanément résolutive ayant duré 2 minutes et 41 secondes. Ce court rapport met l’accent sur le fait qu’une cause rythmique de syncope ne doit pas être écartée chez les patients porteurs du SBr présentant une perte de connaissance très prolongée.
