91 year old female who is a smoker.
Question 1: What causes the difference in P wave morphology in wandering multifocal atrial tachycardia?
Question 2: What is the difference between multifocal atrial tachycardia and wandering atrial pacemaker?
Question 3: What type of patients develop multifocal atrial tachycardia?Question 4: What are some treatment options for this patient's rhythm?
Question 1: The different P wave morphologies occur because they are originating from different areas of the atrium.
Question 2: If the mean heart rate is less than 100 bpm, the rhythm iscalled wandering atrial pacemaker. When the heart rate exceeds 100 it is called multifocal atrial tachycardia.
Question 3: MAT almost always occurs in patients with lung disease, often during an acute exacerbation.
