Plain-English summary
A group of 20 dogs diagnosed with persistent atrial standstill (a heart condition) received pacemakers to help manage their symptoms. On average, these dogs lived about 866 days after the surgery, regardless of whether they died from heart-related issues or other causes. The study found that having congestive heart failure at the time of diagnosis or being of a certain breed did not significantly change how long the dogs survived after getting a pacemaker. Overall, the pacemaker implantation helped improve the dogs' quality of life for a considerable time.

Abstract
OBJECTIVES: To evaluate survival time in dogs with persistent atrial standstill after pacemaker implantation and to compare the survival times for cardiac-related vs. non-cardiac deaths. Secondary objectives were to evaluate the effects of breed and the presence of congestive heart failure (CHF) at the time of diagnosis on survival time. ANIMALS: Twenty dogs with persistent atrial standstill and pacemaker implantation. METHODS: Medical records were searched to identify dogs diagnosed with persistent atrial standstill based on electrocardiogram that underwent pacemaker implantation. Survival after pacemaker implantation was analyzed using the Kaplan-Meier method. RESULTS: The median survival time after pacemaker implantation for all-cause mortality was 866 days. There was no significant difference (p=0.573) in median survival time for cardiac (506 days) vs. non-cardiac deaths (400 days). The presence of CHF at the time of diagnosis did not affect the survival time (P=0.854). No difference in median survival time was noted between breeds (P=0.126). CONCLUSIONS: Dogs with persistent atrial standstill have a median survival time of 866 days with pacemaker implantation, though a wide range of survival times was observed. There was no difference in the median survival time for dogs with cardiac-related deaths and those without. Patient breed and the presence of CHF before pacemaker implantation did not affect median survival time.
