A diagnosis of orthodromic atrioventricular reciprocating tachycardia (OAVRT) was made in a 6-year-old male Boxer based on electrocardiographic and Holter-ECG findings. The surface electrocardiogram showed a narrow-complex tachycardia, with a regular ventricular rhythm ranging from 280 to 300 bpm, QRS alternans, and retrograde P waves present in the late part of ST segment, with a RP'/P'R ratio < 1. The dog was successfully treated short-term with intravenous verapamil, and long-term with procainamide and diltiazem. This report shows the utility of the surface electrocardiogram in the diagnosis of OAVRT with a concealed accessory pathway in the dog, as it was previously reported in human literature.
根据心电图和动态心电图检查结果，对一只6岁雄性拳师犬诊断为顺向型房室折返性心动过速（OAVRT）。体表心电图显示为窄QRS波心动过速，心室节律规整，心率在280至300次/分钟之间，存在QRS波交替现象，ST段晚期可见逆行P波，RP'/P'R比值<1。该犬经静脉注射维拉帕米进行短期成功治疗，并长期使用普鲁卡因胺和地尔硫䓬治疗。本报告显示了体表心电图在诊断犬隐匿性旁路所致OAVRT中的作用，正如之前人类文献中所报道的那样。
