Atrial fibrillation in dogs is a common and clinically significant arrhythmia - particularly in large-breed dogs with structural heart disease such as dilated cardiomyopathy. In this video, we break down canine atrial fibrillation using a mechanism-based ECG approach, explaining exactly what is happening in the atria, the AV node, and on the ECG.

You’ll learn how chaotic atrial electrical activity produces an irregularly irregular rhythm, why organized P waves disappear, and how atrial dilation, fibrosis, and electrical remodeling create the substrate for atrial fibrillation in dogs. We also walk through how continuous atrial impulses bombard the AV node, leading to unpredictable ventricular conduction on ECG.

This veterinary ECG walkthrough focuses on mechanism-based ECG interpretation, not pattern memorization. Topics include canine ECG interpretation, atrial arrhythmias in dogs, AV nodal conduction, and the hemodynamic consequences of atrial fibrillation, including loss of atrial contraction and impaired ventricular filling in dogs with myocardial disease.

This video is designed for veterinary students, interns, residents, and clinicians who want to understand why ECG patterns behave the way they do in canine cardiac arrhythmias.
