Plain-English summary
A Labrador Retriever with exercise intolerance was diagnosed with a serious heart condition called third-degree atrioventricular block, which affects how the heart beats. To help, the veterinarian implanted a new type of pacemaker that uses a special lead to stay securely in place without making it harder for the heart to pace itself. After 19 months, the dog is back to a normal level of activity, showing that this new pacemaker design can be very beneficial for dogs with similar heart issues.

Abstract
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.
