Troubles congénitaux du rythme cardiaque chez l'enfant. Quelles recommandations pour l'anesthésie ?

Congenital dysrhythmias can have 2 origins: Wolff-Parkinson-White syndrome and channelopathies. Various tachycardias can occur in patients suffering from WPW syndrome. The most common tachycardia is supraventricular tachycardia in which a reentrant circuit is created between the atrioventricular node via anterograde conduction and the accessory pathway via retrograde conduction. Intravenous adenosine, in blocking conduction via the atrioventricular node, is the most effective treatment. Arrhythmogenic channellopathies are long QT syndrome, catecholaminergic ventricular tachycardia, Brugada syndrome and short QT syndrome. Recommendations for the anaesthetic management of these patients in the perioperative period are given.
