Un yorkshire de 10 ans est pr\u00e9sent\u00e9 en consultation pour un premier \u00e9pisode syncopal de plusieurs minutes.<\/p>\n

L’examen du chien est enti\u00e8rement normal, aucun souffle cardiaque, ni arythmie ne sont per\u00e7us pau d\u00e9but de la consultation.<\/p>\n

L’\u00e9chocardiographie montre un c\u0153ur normal.<\/p>\n

Un ECG est r\u00e9alis\u00e9:\u00a0 Les QRS sont fins mais les ondes P sont coll\u00e9es au pied de l’onde R. La branche ascendante de l’onde R est parfois emp\u00e2t\u00e9e et on remarque un rythme en accord\u00e9on.<\/p>\n

L’intervalle PR est trop court pour que le rythme soit sinusal.<\/p>\n

Il s’agit d’un rythme jonctionnel.<\/p>\n

L’ensemble de ces anomalies \u00e9voque un syndrome de pr\u00e9-excitation ventriculaire li\u00e9 \u00e0 un faisceau accessoire.<\/p>\n\n\n

Avant la fin de la consultation, le chien refait une syncope et se retrouve en d\u00e9cubitus lat\u00e9ral. Le pouls est difficilement perceptible.<\/p>\n

Un nouveau trac\u00e9 est alors effectu\u00e9:<\/p>\n\n\n

acc\u00e8s de tachycardie jonctionnelle<\/figcaption><\/figure>\n\n\n

Dans cet acc\u00e8s de tachycardie supraventriculaire, la fr\u00e9quence cardiaque d\u00e9passe les 400 bpm.<\/p>\n

Que ce soit pendant la crise ou en dehors de celle-ci, les QRS restent fins. Durant l’acc\u00e8s de tachycardie supraventriculaire, le rythme est r\u00e9gulier et les QRS sont homog\u00e8nes.<\/p>\n

Le m\u00e9canisme mis en jeu, ici, est un faisceau de conduction accessoire, qui, pour la premi\u00e8re fois (le chien a 10 ans), est devenu perm\u00e9able.<\/p>\n

Ainsi, l’influx sinusal emprunte \u00e0 l’aller les voies de conduction nodo-hissiennes habituelles (conduction ant\u00e9rograde) puis remonte ensuite aux oreillettes via le faisceau accessoire (conduction r\u00e9trograde). Et le cycle recommence ainsi pendant plusieurs minutes, r\u00e9alisant une tachycardie jonctionnelle orthodromique.<\/p>\n

Il arrive parfois que l’influx sinusal descende par le faisceau accessoire et remonte par le n\u0153ud AV. Dans ce cas, l’influx descendant sans rencontrer de fibres lentes\u00a0 sur son passage peut \u00eatre conduit jusqu’aux ventricules avec une vitesse tr\u00e8s \u00e9lev\u00e9e (conduction antidromique). Les QRS sont alors \u00e9largis.<\/p>\n

Ici, les QRS sont fins car l’activation ventriculaire se fait exclusivement par les voies de conduction classiques.<\/p>\n\n\n
