Develop your knowledge and understanding of atrial fibrillation in horses. This is a one-part course that can also be taken as part of the Poor performance: cardiac causes course bundle.

This module looks at pathogenesis, diagnosis, treatment, prevention and outcomes of atrial fibrillation in horses, including:
Cause – predisposed by large atrial size and high vagal tone.
Signs – usually poor performance during maximal exercise; may be no clinical signs (incidental finding).
Diagnosis – auscultation, electrocardiography.
Treatment – in otherwise health horses, oral quinidine sulphate or transvenous electrical cardioversion. Attempted cardioversion not recommended for horses with atrial fibrillation secondary to heart failure.
Prognosis – in otherwise healthy horses, good for life, although long-term survival of horses with persistent atrial fibrillation is not known. Cardioversion advised for performance horses; some horses with persistent atrial fibrillation may be able to continue at lower levels of work. In heart failure, prognosis is poor.
