Ectopic Supraventricular Arrhythmias
Wandering atrial pacemaker
Wandering atrial pacemaker (multifocal atrial rhythm) is an irregularly irregular rhythm caused by the random discharge of multiple ectopic atrial foci. By definition, heart rate is≤100 beats/minute. Except for the rate, features are the same as those of multifocal atrial tachycardia. Treatment is directed at causes.
