Atrial Flutter with Poor Ventricular Response in a Bull Terrier Dog

초록

A six-year-old intact female Bull Terrier dog (weighing 17 kg) was referred to the Veterinary Teaching Hospital with exercise intolerance and occasional syncope as the primary complaint. Diagnostic studies revealed a rare case of atrial flutter with complete heart block and aberrant ventricular activation from the ectopic focus, possibly due to idiopathic dilated cardiomyopathy. Although the dog was responded with cardiac medication for right-sided heart failure and anti-arrhythmic agent (dofetilide), the dog died suddenly of cardiac arrest after 11 months of treatment.
