A cardiac gallop rhythm and a low-grade systolic murmur were found in an 8-year-old Miniature Poodle. Conditions had not changed 7 months later, but electrocardiographic evaluation revealed a short R wave, large S wave, prolonged QRS interval and mean electrical axis of -100 degrees, all consistent with a right bundle-branch block. The dog has remained in good condition for 2 years without right-heart enlargement, ectopic beats or tachycardia, indicating the condition was an incidental finding.
一只8岁的迷你贵宾犬被发现有奔马律和轻度收缩期杂音。7个月后情况未变，但心电图评估显示R波短、S波大、QRS间期延长且平均电轴为-100度，均符合右束支传导阻滞。这只狗两年来一直状况良好，没有右心扩大、异位搏动或心动过速，表明该情况是偶然发现。
