Pulmonary vein firing initiating atrial fibrillation in the horse: Oversized dimensions but similar mechanisms

J Cardiovasc Electrophysiol. 2020 May;31(5):1211-1212. doi: 10.1111/jce.14422. Epub 2020 Mar 5.

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.

Keywords: atrial fibrillation; atrial remodeling; equine; mechanisms; pulmonary veins; triggers.
