Beginner ECG 2
Atrial fibrillation with an uncontrolled ventricular response
There are three common heart rhythm disorders that cause an irregularly irregular rhythm:
- Atrial fibrillation
- Atrial flutter with variable conduction
- Multifocal atrial tachycardia, or MAT
With atrial fibrillation, no discrete P waves can be seen; however, coarse “fibrillitory waves” are at times present. In atrial flutter, a “sawtooth” pattern is seen. In MAT, at least three distinct P wave morphologies are present.
