PEARL # 3: Atrial Flutter with 1:1 AV conduction is rare! Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.

Abstract Introduction The use of flecainide and propafenone for medical cardioversion of atrial fibrillation (AF) and atrial flutter/intra-atrial reentrant tachycardia (IART) is well-described in adults without congenital heart disease (CHD).

On the other hand, non-FAAM-guided ablation was performed via linear ablation, complex fractionated atrial electrogram ablation, superior vena cava isolation, and focal ablation according to the location of the non-PV foci. The primary endpoints were AF recurrence, atrial flutter, and/or atrial tachycardia.

A deep neural network for 12-lead electrocardiogram interpretation outperforms a conventional algorithm, and its physician over-read, in the diagnosis of atrial fibrillation. M Y A NSWER: In my experience, MAT is the 2nd-most commonly overlooked cardiac arrhythmia ( surpassed only by Atrial Flutter ).

It is atrial flutter with 2:1 conduction. There are clear flutter waves in lead II across the bottom. In V1, there are upright waves that appear to be P-waves but are not: they are atrial waves and it is typical for atrial flutter waves to be upright in V1, whereas sinus P-waves are biphasic in V1.

Abstract Background Dofetilide is a class III antiarrhythmic agent approved for the treatment of atrial fibrillation and atrial flutter. Given the efficacy of other class III agents, it has been used off-label for the treatment of premature ventricular complexes (PVCs) and ventricular tachycardias (VTs).

There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. There are clearly no flutter waves, so it is not atrial flutter (a "macro-reentrant" atrial tachycardia) Is it AVNRT originating at the superior pole of the AV node, resulting in a retrograde P-wave before the QRS?
