👉 Access the complete Opti ECG case vault here: https://www.opti-ecg.com/ Accelerated Idioventricular Rhythm (AIVR) in dogs is commonly mistaken for ventricular tachycardia - but they are not the same rhythm. In this episode of the Veterinary ECG Case Series, we break down canine AIVR using a mechanism-based ECG approach and show you how to differentiate it from true ventricular tachycardia. This case involves a Labrador with a bleeding splenic mass and hemoabdomen, where systemic stress, hypovolemia, hypoxia, and catecholamine surge trigger enhanced ventricular automaticity. You will learn how pacemaker competition between the sinus node and ventricular myocardium creates: Wide QRS complexes AV dissociation Fusion beats Capture beats A ventricular rate typically between 60–160 bpm This case highlights a critical clinical principle: treat the patient, not the ECG. In dogs with splenic masses, GDV, trauma, or shock, AIVR often resolves once the underlying cause is corrected - and unnecessary antiarrhythmic therapy may be dangerous. This video is designed for veterinary students, emergency clinicians, and general practitioners who want to understand ventricular arrhythmias logically -not just recognize wide QRS complexes. 💬 Comment below: which canine or feline rhythm should we break down next?
