A nine-year-old male neutered domestic Shorthair cat presented on referral for evaluation. The cat presented to its primary veterinarian for acute onset vomiting, panting, and weakness. An electrocardiogram performed at the regular veterinarian was concerning for ventricular tachycardia, and the cat was referred for further evaluation. An echocardiogram revealed hypertrophic cardiomyopathy, and a review of the electrocardiogram revealed findings suggestive of ventricular pre-excitation alternans with the suspect pre-excited complexes appearing to alternate with sinus complexes. This is the first reported case of pre-excitation alternans in a cat.
一只九岁已绝育的雄性家养短毛猫因转诊前来评估。这只猫最初因急性呕吐、气喘和虚弱被送往其主治兽医处。常规兽医处进行的心电图检查显示有室性心动过速，于是这只猫被转诊做进一步评估。超声心动图显示患有肥厚型心肌病，复查心电图发现有提示室性预激交替现象的表现，可疑的预激复合体似乎与窦性复合体交替出现。这是首例报道的猫的预激交替现象病例。
