Introduction

A 12-year-old 2.5-kg sexually intact male Pomeranian mix was presented for pacemaker interrogation 2 weeks following placement of a transvenous VVI pacemaker with active lead fixation. The pacemaker was placed following episodes of collapse secondary to third-degree atrioventricular (AV) block. Examination, radiographic, and echocardiographic findings prior to pacemaker implantation were consistent with stage B1 chronic degenerative valve disease. The dog was bright and alert on presentation and was reported to be asymptomatic by the owner, other than frequent head shaking since surgery. The owner reported a heart rate at home ranging from 60 to 80 beats/min. On physical examination,
