ATRIAL FLUTTER DEGENERATES INTO ATRIAL FIBRILLATION

ECG Guru

Atrial flutter and atrial fibrillation are 2 different cardiac arrhythmias, but occur frequently side by side in the same patient. Here is an example of how atrial flutter degenerataes into atrial fibrillation.

Long-term outcomes after catheter ablation for idiopathic atypical atrial flutter

HeartRhythm

Idiopathic atypical (non-cavotricupid isthmus [CTI]-dependent) atrial flutter (IAAFL) may be seen in patients without structural heart disease and without previous cardiac surgery or ablation.

Atypical Atrial Flutter

ECG Guru

Why is this left atrial atypical atrial flutter ( ECG 1 )? Atrial fibrillation can be excluded because nice flutter waves (all look the same) can be clearly identified. The flutter waves are positive in V1 ( ECG 2 ). The flutter waves are positive in V1 ( ECG 2 ).

Association of typical atrial flutter and cavotricuspid isthmus ablation on clinical recurrence after cryoballoon ablation for atrial fibrillation

Frontiers in Cardiovascular Medicine

Typical atrial flutter commonly occurs in patients with atrial fibrillation (AF). Limited information exists regarding the effects of concurrent atrial flutter on the long-term outcomes of rhythm control. Patients who were screened for typical atrial flutter were included in the analysis ( n  = 1,907).

A young woman with palpitations. What med is she on? With what medication is she non-compliant? What management?

Dr. Smith's ECG Blog

Atrial flutter with 2:1 conduction. The atrial flutter rate is approximately 200 bpm, with 2:1 AV conduction resulting in ventricular rate almost exactly 100 bpm. Further history revealed she had new onset atrial flutter soon after her aortic surgery, and was put on flecainide approximately 1 month ago.

Atrial Flutter With Right Bundle Branch Block and Left Anterior Fascicular Block In a Patient With Preexisting RBBB + LAFB

ECG Guru

If a wide complex tachycardia occurs, the probability is very high that it is a ventricular tachycardia (approx. 80%, in patients with a previous myocardial infarction (.) Here we see a broad complex tachycardia that looks like an RBBB + LAFB, which is regular. In this constellation, 3 causes must be considered: 1.
