Multifocal Atrial Tachycardia ECG Interpretation #312


Multifocal Atrial Tachycardia

  • Multifocal Atrial Tachycardia is just a faster version of Wandering Atrial Pacemaker. The criteria is the same as Wandering Atrial Pacemaker with the only difference being the heart rate exceeds 100 bpm.
  • These changes in the locus of stimulation within the atria affect the morphology of the P waves.
  • Remember, you must observe at least three different shaped P waves.
  • Due to the presence of irregular R to R intervals coupled with the changing P wave morphology, some people have confused this rhythm with Atrial Fibrillation.
