The drug flecainide may change the way veterinarians treat atrial fibrillation in horses, according to veterinarians at the University of Wisconsin School of Veterinary Medicine in Madison. Large animal internal medicine veterinarians Ase Risberg and Sheila McQuirk administered the drug orally to resolve a chronic case of atrial fibrillation in a horse, the school reported. Flecainide has been administered intravenously to horses in Japan and England, but Dr. Risberg believes this is the first time it has been administered orally or used in horses in the United States. <HOME>
