Abstract
Complex ventricular arrhythmias were diagnosed in an asymptomatic 3-month-old female Dachshund. Based on the patient's signalment, electrocardiographic findings and exclusion of other differentials, a channelopathy was suspected. The dog was treated with oral sotalol, mexiletine and magnesium supplementation. This case report demonstrates the use of ambulatory electrocardiogram analysis and the complexity of assessing arrhythmia mechanisms, and discusses the approach to, and treatment of, ventricular arrhythmias in this case.
