Karen Coumbe: A vet’s point of view on atrial fibrillation [H&H VIP]

Atrial fibrillation (AF) is the most common irregularity of the heart rhythm that will affect a horse’s performance. If the affected horse is not an athlete, it may be able to cope with this sort of cardiac irregularity, since the horse’s heart is a strong and efficient pump, so it can still push enough blood around for a horse to do light work, even if this pump is not working correctly.
