This is the first report of paroxysmal atrioventricular block with Wenckebach cycles in a dog exhibiting syncope. The patient was a 1-year-old female Shiba Inu referred to our hospital with chief complaints of exercise intolerance, dizziness during walking, and tongue discoloration. Pacemaker implantation was performed based on the clinical presentation and Holter electrocardiogram findings. In this case, long-term management was successfully achieved for 13 years and 3 months (Age 15 years old) after the placement of pacemaker. A histopathological examination revealed that no abnormalities in the conduction system were detected that could explain the arrhythmia. Consequently, the arrhythmia was suspected to have been caused by vagus nerve stimulation.
这是关于一只出现晕厥的犬发生伴有文氏周期的阵发性房室传导阻滞的首例报告。该患者为一只1岁雌性柴犬，因运动不耐受、行走时头晕和舌头发紫等主要症状转诊至我院。根据临床表现和动态心电图检查结果进行了起搏器植入。在这种情况下，起搏器植入后成功实现了13年零3个月（15岁）的长期管理。组织病理学检查显示，未发现传导系统存在可解释心律失常的异常情况。因此，怀疑心律失常是由迷走神经刺激引起的。
