She also has a hx of paroxysmal atrial fibrillation and is on oral anticoagulant treatment. The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. The last echocardiography 12 months ago showed HFmrEF.

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).

Procedures were most commonly for atrial fibrillation (52.4%), atrial flutter (10.9%), and atrioventricular nodal re-entrant tachycardia (10.1%). Results 1089 patients were included: MC 718 (65.9%); Fo8 HT 105 (9.6%); Fo8 MOD 266 (24.4%). 01; minor: MC 16.5%, Fo8 HT 12.0%, Fo8 MOD 7.4%, p =.002).

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?

ABSTRACT Background Different ablation strategies have been developed for persistent atrial fibrillation (PeAF), but early management is still controversial. In the clinical setting of PeAF, the safety and efficacy of early Marshall plan have not yet been fully studied.
