Ce trac\u00e9 caract\u00e9ristique d’une dysfonction sinusale s\u00e9v\u00e8re est celui d’un chien de 12 ans (5 kg) est en tr\u00e8s mauvais \u00e9tat g\u00e9n\u00e9ral, il ne peut pas se tenir debout et sa temp\u00e9rature est de 35,6\u00b0C . Il ne montre pas d’anomalies notoires \u00e0 l’\u00e9chocardiographie. Seul un discret \u00e9paississement des parois du ventricule gauche est not\u00e9. La pression art\u00e9rielle systolique est mesur\u00e9e \u00e0 135 mmhg.<\/p>\n

La num\u00e9ration-formule sanguine est dans les normes, de m\u00eame que les examens biochimiques.<\/p>\n

La kali\u00e9mie est de 6,85 mEQ\/L. Le cortisol n’a pas \u00e9t\u00e9 dos\u00e9.<\/p>\n

Sur ce trac\u00e9, on note un rythme sinusal \u00e0 22 bpm. Les QRS sont larges (environ 70 ms) et il existe un bloc atrioventriculaire du 1er degr\u00e9 (PR: 190 ms). Par ailleurs, les ondes P sont bifides, ce qui t\u00e9moigne d’un bloc inter-atrial puisque l’oreillette gauche n’apparait pas dilat\u00e9e \u00e0 l’\u00e9chographie.<\/p>\n

Ce chien arriv\u00e9 12h plus t\u00f4t pr\u00e9sentait un taux de T4 < 6 pmol\/L et un trouble du rythme alternant extrasystoles atriales et salves d’extrasystoles ventriculaires (voir ci-dessous)<\/p>\n\n\n

Sur ces trac\u00e9s, on remarque des ondes P n\u00e9gatives en D2, D3 et AVF, t\u00e9moignant d’un rythme issu du sinus coronaire. La fr\u00e9quence est d’environ 110 bpm. Les QRS sont fins et non hypovolt\u00e9s.<\/p>\n
