Permanent pacemakers are commonly used in veterinary practice and can have a dramatic effect on the treatment of heart block. A Labrador Retriever dog suffering from exercise intolerance secondary to third degree atrioventricular block was treated with a new pacemaker system. A steroid-eluting screw-in type lead that has the advantage of being more fixed to the myocardial wall without increasing the pacing threshold was used. The heart rate was regulated with an acceleration sensing pacemaker generator that included several automatic modulation systems. Nineteen months after implantation, the dog has a normal level of activity. The present case suggests that this pacemaker design may offer important advantages for canine patients.
永久性起搏器在兽医临床中常用，对心脏传导阻滞的治疗可产生显著效果。一只患有继发于三度房室传导阻滞的运动不耐受的拉布拉多猎犬接受了一种新型起搏器系统的治疗。使用了一种类固醇洗脱螺旋式导线，其优点是在不增加起搏阈值的情况下更牢固地固定在心肌壁上。心率通过一个包含多个自动调节系统的加速度感应起搏器发生器进行调节。植入后19个月，这只狗的活动水平正常。本病例表明，这种起搏器设计可能为犬类患者带来重要优势。
