A 10-month-old female domestic shorthaired (DSH) cat was presented with peracute respiratory problems. Physical examination revealed dyspnoea, tachypnoea, cyanosis, weak pulse and bradycardia. Auscultation showed pulmonary crepitation and attenuated heart sounds and a pansystolic grade V/VI murmur. The electrocardiogram showed atrioventricular dissociation identified as third-degree sinoatrial block. X-rays showed increased density in the ventral and middle zones of the thorax and loss of definition of the cardiac silhouette and increased diffuse radiographic density of the entire abdomen. Echocardiography revealed dilatation of the right atrium and concentric biventricular hypertrophy. A type 1 persistent truncus arteriosus was diagnosed at necropsy. This is the first case report of this type of arrhythmia in a cat with persistent truncus arteriosus, and its relationship with the described congenital cardiac anomaly is discussed.
一只 10 月龄的雌性家养短毛猫（DSH）出现急性呼吸问题。体格检查显示呼吸困难、呼吸急促、发绀、脉搏微弱和心动过缓。听诊显示肺部有湿啰音，心音减弱，并伴有全收缩期 V/VI 级杂音。心电图显示房室分离，确诊为三度窦房传导阻滞。X 射线显示胸部腹侧和中部区域密度增加，心影边界不清，整个腹部弥漫性射线密度增加。超声心动图显示右心房扩张和双心室同心性肥厚。尸检诊断为 1 型永存动脉干。这是首例永存动脉干猫出现这种类型心律失常的病例报告，并讨论了其与所描述的先天性心脏异常的关系。
