Plain-English summary
Atrial fibrillation, a heart condition where the heart beats irregularly, can be triggered by the pulmonary veins in humans. This study looked into whether the same thing happens in horses, as we don't fully understand how this condition works in different species. Researchers used a special mapping technique to observe the heart's electrical activity in horses while they were awake and without using X-ray guidance. The findings suggest that the pulmonary veins can also play a role in causing atrial fibrillation in horses, similar to what is seen in humans.
Abstract
Atrial fibrillation is triggered by the pulmonary veins in humans. Although atrial fibrillation is known to occur in other species, the mechanisms of disease in these are not known. Here we present evidence for pulmonary vein triggers in the horse, where 3D HD Grid mapping was undertaken in the conscious state in the absence of fluoroscopy.
