WAP & Multifocal Atrial Tachycardia — ECG Academy Lesson

Identify wandering atrial pacemaker and multifocal atrial tachycardia on a rhythm strip by recognizing at least three different P wave morphologies, understand the rate distinction between WAP and MAT, and differentiate both from atrial fibrillation.

Learning Objectives

• Define wandering atrial pacemaker (WAP) and state its diagnostic criteria
• Define multifocal atrial tachycardia (MAT) and explain how it differs from WAP
• Identify at least three different P wave morphologies on a rhythm strip
• Differentiate MAT from atrial fibrillation based on identifiable P waves
• Describe the clinical conditions most commonly associated with MAT
• State the appropriate monitor tech response when MAT is identified
