"eqz_remarque": "L'ECG en tachycardie est régulier à QRS larges. Cependant, l'arrêt reproductible par manoeuvres vagales ou striadyne évoque fortement une tachycardie jonctionnelle. Sur l'ECG en rythme sinusal, on observe une pré excitation ventriculaire droite (QRS pré excités négatifs en V1). Les 2 diagnostics les plus probables sont alors une tachycardie antidromique sur voie accessoire ou éventuellement une tachycardie orthodromique avec bloc de branche. L'aspect en tachycardie avec la partie initiale des QRS empâtées évoque plutôt une tachycardie antidromique. Si les tachycardies antidromiques sont plus rares que les tachycardies orthodromiques, certaines voies accessoires atypiques (faisceaux atriofasciculaires de Mahaim le plus souvent le long de l'anneau tricuspide) ont des propriétés particulières avec conduction décrémentielle uniquement antérograde avec donc uniquement des tachycardies antidromiques.", | |||
