Typical Atrial flutter
- Typical Atrial flutter produces a “sawtooth” pattern to the flutter waves – especially in the inferior ECG leads
- Other forms morphologically and/or in location have been considered as “atypical” flutter.
- Typical AFl presents as a “sawtooth” pattern on the ECG – with inverted flutter (F) waves in the inferior leads and upright F waves in V1.
How to differentiate Atypical Flutter from Typical Flutter?
Three findings that distinguish Atypical atrial flutter arrhythmia from typical atrial flutter:
Atypical Atrial Flutter
- Flutter rate is faster at 375 beats/minute
- There is no isoelectric interval between the flutter waves
- There is more apparent positivity in leads II, III, and avF.
