Ventricular Tachycardia: ECG Diagnosis

Ventricular Tachycardia: ECG Diagnosis is organized by Acadoodle.

Expiration Date: 06-DEC-2026

Overview:
In this course, we explain the re-entrant mechanism generating ventricular tachycardia in the setting of structural heart disease. We explain the mechanism underlying incomplete AV dissociation in a ventricular tachycardia. We will teach you how to recognise this diagnostically important phenomenon on the ECG. You will learn how to divide cases of broad complex tachycardia into right or left bundle branch block morphologies. We teach you aspects of ECG analysis which will help you to make the crucial distinction between VT and SVT with aberrancy. You will learn how to interpret the presence or absence of a response to intravenous adenosine in a broad complex tachycardia. We discuss variants of ventricular tachycardia occurring in the absence of structural heart disease and their identification on the ECG. We will also teach you how to recognise artefact on the ECG mimicking VT (‘pseudo-ventricular tachycardia’). We detail the terminology used in the description of ventricular tachycardia. The ‘essential reading’ section of the bibliography contains links to papers which have been selected to reinforce and enhance the lessons learned in the videos. These papers should be read before attempting the quiz. In the quiz, we present informative clinical cases which will confirm that you have acquired the skills listed in the learning objectives of this course and which will, reinforce those skills.

Learning Objectives:
Upon successful completion of this activity, you will be able to:

• Define the term ventricular tachycardia
• Explain the re-entrant mechanism underlying ventricular tachycardia in structural heart disease
• Determine the bundle branch block morphology of a broad complex tachycardia
• Recognize ECG evidence of AV dissociation during a broad complex tachycardia
• Appropriately utilize and interpret the response to intravenous adenosine in a broad complex tachycardia
• Avoid administration of intravenous adenosine in cases of atrial fibrillation with aberrancy
• Use appropriate language in the description of VT
• Identify pseudo-ventricular tachycardia on the ECG, thereby avoiding inappropriate medical intervention
