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.

A fully upright P-wave is typical atrial activity of atrial flutter as seen in V1. See these example cases of upright P-waves: Case Continued Thus, I was all but certain that this was atrial flutter. IV Digoxin may begin to slow the ventricular response of AFib or AFlutter sooner than many clinicians realize.

To me, it was clearly atrial flutter with 1:1 conduction. The rate of 280 is just right for atrial flutter. The waves look like atrial flutter waves, NOT like a wide ventricular complex. Reverted to atrial fibrillation with RVR while in the hospital 3 times and needed cardioversion.

The rhythm differential for narrow, regular, and tachycardic is sinus rhythm, SVT (encompassing AVNRT, AVRT, atrial tach, etc), and atrial flutter (another supraventricular rhythm which is usually considered separately from SVTs). Therefore this patient is either in some form of SVT or atrial flutter. If so, why?

This narrows our differential for the rhythm down to sinus tachycardia, paroxysmal supraventricular tachycardia (PSVT, or SVT), and atrial flutter. The patient’s history is notable for paroxysmal atrial fibrillation, which raises clinical suspicion for atrial flutter, since these two entities frequently coexist on a spectrum.

Instead, the rate of 150, plus the history of AF, suggested atrial flutter. A close inspection of lead II showed P or flutter waves at a rate of about 300 bpm, also supporting atrial flutter. There appear to be flutter waves at a rate of 300. Flecainide encourages new atrial flutter.

Rate of recurrence did not differ between those who had the procedure before or after 2018. Atrial Tachycardia (70%) and Typical Atrial Flutter (65%) were the most common SVTs ablated. During the 5-year follow up period, 13 (59%) patients with follow up had cardiovascular (CV) hospitalization and 1 patient died.
