Behaviour of the heart rate of horses with auricular fibrillation during exercise and after treatment.
Abstract: Cardioversion through varying quinidine sulphate treatments was achieved in 3 riding horses with auricular fibrillation. The horses were subjected to continual telemetric ECG registration before and after reversion in a uniform exercise-tolerance-test. A comparison of the heart rate curves showed a strong decline of the heart beat frequency during the exercise phase after synchronisation. The decrease in heart rate during exercise was greater than 30% in all 3 patients. Anti-arrhythmic treatment is, therefore, recommended for horses with auricular fibrillation and without concurrent heart disease.

The research conducted investigates the impact of quinidine sulphate treatments on riding horses affected by auricular fibrillation. It reveals a significant decline in heart rate during exercise after the treatment has been applied, suggesting that horses with auricular fibrillation, not suffering from other heart diseases, could benefit from an anti-arrhythmic treatment.
Overview
- This research article explores the behavior of heart rates in horses that have auricular fibrillation, during exercise and post-treatment.
- The treatment administered is a type of cardioversion using different quinidine sulphate treatments.
- The subjects of this research are three riding horses.
Methods
- ECG registration was implemented continually on the horses before and after they underwent treatment.
- The results of the treatment were studied under uniform exercise-tolerance-tests, which facilitated comparisons of heart rate curves both pre and post-reversion.
Findings
- The research discovery suggests a noteworthy drop in the heart beat frequency of the horses during the exercise phase following synchronisation.
- This decrease was more than 30% in all three patients during exercise.
Recommendations
- Results suggest anti-arrhythmic treatment could be potentially beneficial for horses diagnosed with auricular fibrillation, especially if they don’t have any other underlying heart ailments.
- Further research is necessary to gather more data and corroborate these initial observations.
