Plain-English summary
A 2-year-old Thoroughbred racehorse developed a fast heart rhythm called ventricular tachycardia after undergoing surgery to fix its throat and heart. During the operation, the horse had a slight fever and experienced a temporary increase in carbon dioxide levels. To treat this condition, the horse received an intravenous infusion of a medication called quinidine gluconate. The veterinarians closely monitored the horse's heart rhythm during treatment, and after 12 hours, the horse's heart rhythm returned to normal. The exact reason for the fast heart rhythm was not identified.
Abstract
A 2-year-old Thoroughbred racehorse developed ventricular tachycardia after elective laryngoplasty and ventriculectomy were performed while anesthesia was maintained with halothane. During surgery, the horse became febrile and developed transient mild hypercarbia. The horse was treated with an IV infusion of quinidine gluconate. Continuous electrocardiographic monitoring was used to evaluate cardiac rhythm during treatment, and conversion was achieved after 12 hours of IV infusion. The inciting cause for the arrhythmia was not determined.
