Tachycardie supraventriculaire \u00e0 300 bpm<\/figcaption><\/figure>\n\n\n\n

Ce bouledogue fran\u00e7ais de 15 kg pr\u00e9sente une dyspn\u00e9e importante en rapport avec une pneumopathie. <\/p>\n\n\n\n

L’\u00e9chocardiographie montre une dilatation mod\u00e9r\u00e9e du ventricule droit et un l\u00e9ger \u00e9paississement des parois du ventricule gauche. <\/p>\n\n\n\n

Le trac\u00e9 \u00e0 50 mm\/s permet d’individualiser les ondes P et de pr\u00e9ciser l’origine supraventriculaire de cette tachycardie. L’intervalle PR de 80 ms pour une fr\u00e9quence de 300 bpm est compatible avec une origine sinusale. Cependant, on ne peut exclure une tachycardie atriale ectopique en l’absence d’enregistrement en dehors de cet \u00e9pisode.<\/p>\n","protected":false},"excerpt":{"rendered":"
