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).

ABSTRACT Atrial flutter (AFL), defined as macro-re-entrant atrial tachycardia, is associated with debilitating symptoms, stroke, heart failure, and increased mortality. Atypical AFL is a heterogenous group of re-entrant atrial tachycardias that most commonly occur in patients with prior heart surgery or catheter ablation.

In the first section of the ECG we see coarse fibrillation waves and QRS complexes with very different RR intervals, which is why this is atrial fibrillation. It is not atrial flutter because the fibrillation waves are of different size and polarity (depending on the lead) and the intervals between the atrial actions are irregular.

If it is slow Atrial flutter with 1:1 conduction, it should slow the conduction and reveal the flutter waves. This is the exact rate one expects with slow atrial flutter and it is why slow atrial flutter can be so dangerous: it conducts 1:1, with fast ventricular rates. Rate 120, flutter rate 240.

Let's first consider the heart rate: with a heart rate of 194 beats/min, the heart rate is too low for atrial flutter (1:1) (except in patients who have been pre-treated with medication), and the rate would be unusually high for atrial flutter with 2:1 conduction. What arrhythmia is present?
