Tachycardie ventriculaire idiopathique incessante chez le nourrisson : à propos d'un cas

Résumé

Incessant ventricular tachycardia is rare in childhood and usually difficult to treat. We report a case of incessant idiopathic ventricular tachycardia in a 9 month-old child complicated by tachycardia mediated cardiomyopathy. The arythmia was resistant to Vagal maneuvers, multiple doses of adenosine and also to electrical cardioversion. However, cardioversion was achieved with high dose of amiodaronne (800mg/m2sc/day). The heart has recovered a normal left ventricule function after 15 days of treatment. No recurrence of arrhythmia was observed during 4 years of follow up.
