Plain-English summary
Two young Labrador retrievers were experiencing fainting spells due to a slow heart rate caused by atrial myopathy (a heart condition). They both received permanent pacemakers to help regulate their heartbeats. While the pacemakers worked for several years, both dogs eventually developed heart failure and had to be managed with medications for about seven years. Sadly, they were ultimately euthanized due to worsening heart failure and concerns about their quality of life.

Abstract
Two young Labrador retriever dogs with bradycardia-induced syncope resulting from atrial myopathy underwent permanent transvenous pacemaker implantation. Both dogs developed heart failure 3-5 years after pacemaker implantation. Both were managed medically for approximately 7 years after pacemaker implantation and, ultimately, were humanely euthanized due to refractory heart failure signs and quality of life concerns. Long-term management of dogs with atrial myopathy and secondary atrial standstill with pacemaker implantation and medical therapy for heart failure is feasible and prognosis may be better than previously reported or speculated.
