Both atria develop from a combination of the primitive atrium, sinus venous, and pulmonary veins.It In contrast to other tachycardias, with atrial fibrillation (AF), the focus is often speculative, and ablation attempts are made accordingly. We know atrial flutters can be confined to one atrium. Let us see few factors.

Initial assessment with electrocardiography revealed a regular narrow complex tachycardia with 2:1 atrioventricular (AV) relationship, no clear isoelectric baseline and positive P waves in lead V1 consistent with an atrial flutter of left atrial origin with a rapid ventricular rate (~160/min) ( figure 1A ).

Pulmonary vein isolation (PVI) remains the cornerstone of atrial fibrillation (AF) ablation. In patients with more advanced AF subtypes, atypical atrial flutter, and extensive atrial myopathy, additional linear ablation is often required; however, durable block of these remains challenging.

Background The value of empirical superior vena cava isolation (SVCI) following pulmonary vein isolation (PVI) to improve the efficacy of radiofrequency catheter ablation (RFCA) for paroxysmal atrial fibrillation (PAF) remains controversial. RFCA was guided by quantitative AI in both groups.

Re-entrant tachycardias (atrial flutter, PSVT, AVRT, VT) have constant regular heart rates, whereas sinus tachycardia will usually gradually change rate with differing conditions (for instance, after infusion of fluid and BP increase, sinus tach rate might decrease from 130 to 125, for instance). So there is a re-entrant rhythm.

The bedside echo showed a large RV (Does this mean there is a pulmonary embolism as the etiology?) The rhythm is 2:1 atrial flutter. The flutter waves can conceal or mimic ischemic repolarization findings, but here I don't see any obvious findings of OMI or subendocardial ischemia. Lots of info here.

FAAM ablation successfully decreased the recurrence rate of atrial tachyarrhythmia compared with conventional non-PV foci ablation. Abstract Introduction Treatment of recurrent atrial fibrillation (AF) is sometimes challenging due to non-pulmonary vein (PV) foci. The RHYTHMIA system was used to perform all the procedures.
