Ce trac\u00e9 est r\u00e9alis\u00e9 quelques heures apr\u00e8s la d\u00e9fenestration de ce chat.<\/p>\n

La fr\u00e9quence cardiaque est de 270 bpm.  L’onde T est g\u00e9ante et son d\u00e9but est sur-\u00e9lev\u00e9 de pr\u00e8s de 2 mm par rapport \u00e0 la ligne de base, alors que l’amplitude des QRS ne d\u00e9passe pas 0,25 mV.<\/p>\n

L’\u00e9chographie ne met en \u00e9vidence qu’un l\u00e9ger \u00e9paississement des parois ventriculaires, sans rapport avec l’accident et sans r\u00e9percussions cliniques.<\/p>\n

sus-d\u00e9calage ST et onde de Pardee<\/figcaption><\/figure>\n\n\n

Le point J correspond\u00a0 \u00e0 l’intersection de la fin du QRS et du d\u00e9but de l’onde T. Il sert \u00e0 mesurer le d\u00e9calage du d\u00e9but de la repolarisation (onde T) par rapport \u00e0 la ligne de base.<\/p>\n

L’onde T g\u00e9ante, appel\u00e9e aussi onde de Pardee, se rencontre dans diff\u00e9rentes situations (hypothermie, infarctus du myocarde).<\/p>\n

Ce trac\u00e9 permet de suspecter un infarctus d’origine traumatique (l\u00e9sion du r\u00e9seau coronarien).<\/p>\n

Ces l\u00e9sions myocardiques d’origine traumatique ne sont pas exceptionnelles chez le chat comme le montre le trac\u00e9 ci-dessous r\u00e9alis\u00e9, lui aussi, sur un chat d\u00e9fenestr\u00e9. Sur cet animal, l’\u00e9chographie ne fait apparaitre aucune anomalie.<\/p>\n
