Not very often. Oral positive chronotropes (increasers of heart rate) such as propantheline, terbutaline, or theophylline may be used but they're generally inadequate in my hands. The prognosis for these patients with pacemaker placement is generally good to excellent. Clinical signs resolve in 92% of dogs and 1 year survival is 86%. I understand that such an implant may be inappropriate at her age, however.
