摘要

一只9岁的户外意大利猎犬因呕吐和腹泻后发生的严重体温过低而被转诊。在就诊时，心电图显示心室反应缓慢，瞬时心率在20 - 115次/分之间。QRS复合物轻度增大，随后出现J波。QT间期延长（360毫秒）。还观察到多个宽QRS复合物具有各种奇怪的形态，无论是单一的还是成对的，表明心室异位搏。这只狗被送进了医院，并积极地恢复了体温；心律自发转化为窦性心律伴呼吸性窦性心律失常。

Slow ventricular response atrial fibrillation and J wave in a hypothermic dog

A 9-year-old, outdoors, Italian hound dog was referred for severe hypothermia that had occurred after vomiting and diarrhea. At presentation, the electrocardiogram showed a slow ventricular response atrial fibrillation with an instantaneous heart rate ranging from 20 to 115 beats/min. The QRS complexes were mildly enlarged and followed by a J wave. The QT interval was prolonged (360 msec). Multiple wide QRS complexes with various bizarre morphologies, either singular or in couples, indicative of ventricular ectopic beats, were also observed. The dog was hospitalized and actively rewarmed; the rhythm spontaneously converted to sinus rhythm with respiratory sinus arrhythmia.
