Abstract
Bidirectional ventricular tachycardia is a rare variety of tachycardia with a morphologically
distinct presentation. The QRS axis and/or morphology alternate in the frontal plane
leads. We report a patient with bidirectional ventricular tachycardia in association
with aconitine poisoning.
Résumé
La tachycardie ventriculaire bidirectionnelle est une forme rare de tachycardie qui
se manifeste d’une manière morphologiquement distincte. L’axe et/ou la morphologie
des QRS alternent dans les dérivations du plan frontal. Nous rapportons le cas d’un
patient souffrant de tachycardie ventriculaire bidirectionnelle en association avec
un empoisonnement à l’aconitine.
