Atrial Arrhythmias ECG 1

1. Atrial fibrillation with an uncontrolled ventricular response

There are three common heart rhythm disorders that cause an irregularly irregular rhythm:

  1. Atrial fibrillation
  2. Atrial flutter with variable conduction
  3. Multifocal atrial tachycardia (MAT).

With atrial fibrillation, no descrete P waves can be seen, however sometimes coarse "fibrillitory waves" are present. In atrial flutter a "sawtooth" pattern is seen. In MAT there are at least 3 distinct P wave morphologies present.
