摘要

A 6-year-old castrated male Golden Retriever was diagnosed with severe subaortic stenosis with severe left atrial enlargement and high heart rate due to atrial fibrillation. Treatment with digoxin and diltiazem to control ventricular response rate was initiated. Ambulatory electrocardiographic monitoring (Holter monitoring) was performed at the beginning of treatment and was repeated to evaluate the patient's response to drug therapy. Drug dose adjustments were made based on response to therapy as assessed by Holter monitoring. The dog experienced sudden death at home 19 days after beginning treatment while wearing the Holter monitor. Analysis of the Holter recording revealed marked increase in number and complexity of ventricular arrhythmias. A ventricular premature complex occurring on a T wave (R on T) was noted preceding the polymorphic ventricular tachycardia. This arrhythmia immediately degenerated into ventricular fibrillation followed by asystole. This case report describes the arrhythmia that preceded cardiac arrest and reviews the risk factors that could have potentiated the fatal arrhythmia in this dog.
