Complete heart block in cats can appear deceptively stable - particularly when the escape rhythm is relatively fast. In this episode of the Veterinary ECG Case Series, we walk through a mechanism-based ECG interpretation of complete (third-degree) atrioventricular block in cats.

Using a real clinical scenario, this video explains how normal atrioventricular conduction works, what happens when AV conduction is completely lost, and how this appears on the ECG. You’ll learn how to recognize complete AV dissociation, with regular P waves and regular QRS complexes that have no consistent relationship.

We also break down ventricular and junctional escape rhythms in cats, explaining why junctional escape rhythms are common, why QRS complexes are often narrow, and why QRS width reflects the level of the escape pacemaker - not whether atrial impulses are conducting. This is a key interpretation point that often leads to confusion.

This video is designed for veterinary students, interns, residents, and clinicians who want to understand why ECG patterns behave the way they do in feline cardiac arrhythmias - not just recognize them visually.
