Question: what is the difference between wandering atrial pacemaker and multifocal atrial tachycardia?
Answer: Wandering atrial pacemaker is similar to multifocal atrial tachycardia except the heart rate is normal ― that is, less than 100 beats per minute. Wandering atrial pacemaker occurs when multiple areas (ectopic foci) within the atrium generate consecutive action potentials that are all conducted to the ventricles.
