Multifocal Atrial Tachycardia

So the name pretty much tells you exactly what it is and if you have somewhat of a background reading ECGs you could probably guess what it would look like.
Multifocal indicates the atria are receiving stimulation from more than one pacemaker foci. This will result in different p-wave formations on the ECG.
- The requirement for diagnosis is that there are at least three distinct p-wave morphologies. These ECGs might have:
  - A “taller” p-wave
  - A “more pointed” p-wave
  - An inverted p-wave
  - Irregularly irregular rhythm
Tachycardia means that there is a heart rate above 100 beats per minute. And because there is no block at the atrioventricular node, the depolarization will propagate from the atria to the ventricles.
In order to treat the multifocal atrial tachycardia, you will treat the underlying condition.
- It is usually associated with COPD and congestive heart failure.
- So the therapeutics are focused on increasing ventilation and oxygenation
