\"Aspects
ECG de MVD stade 2 ISACHC<\/figcaption><\/figure>\n\n\n

L’ECG ci-dessus (enregistr\u00e9 \u00e0 5 mm\/mV) est celui d’un yorkshire de 5 kg.  Le rythme est sinusal \u00e0 180 bpm. L’arythmie respiratoire a disparu.<\/p>\n

En premier lieu on remarque une amplitude inhabituelle des QRS (3,46 mV en D2 et 3,17 mV en AVF) alors qu’elle devrait \u00eatre de l’ordre de 2 mV chez un chien de ce format.<\/p>\n

Les ondes P sont \u00e9galement hypervolt\u00e9es (0,66 mV) et \u00e9largies (50 ms).<\/p>\n

La dur\u00e9e des QRS d\u00e9passe 60 ms alors que la d\u00e9flexion intrins\u00e9co\u00efde n’est pas significativement augment\u00e9e.<\/p>\n

Les ondes T sym\u00e9triques, pointues et de grande amplitude peuvent \u00eatre rattach\u00e9es \u00e0 une hypertrophie du ventricule gauche.<\/p>\n

L’axe des QRS \u00e0 80\u00b0 est dans les normes.<\/p>\n

Il existe donc, sur ce trac\u00e9, des signes d’insuffisance cardiaque globale.<\/p>\n

L’\u00e9chocardiographie met en \u00e9vidence une endocardiose mitrale et tricuspide ainsi qu’une rupture partielle des cordages tendineux.<\/p>\n

Cela a entrain\u00e9 une augmentation franche du ventricule gauche et, dans une moindre mesure, du ventricule droit. L’oreillette gauche apparait tr\u00e8s dilat\u00e9e. Le chien pr\u00e9sentait un \u0153d\u00e8me pulmonaire p\u00e9ri-hilaire au moment de l’examen.<\/p>","protected":false},"excerpt":{"rendered":"
