2018 Atrial Flutter Tachycardia

There is a regular wide complex tachycardia. 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. If it is flutter, it will reveal the underlying flutter waves.

Wide-complex tachycardia: VT or aberrant, or "other?" The patient had a history of paroxysmal atrial fibrillation and several cardioversions. A wide-complex tachycardia in an older patient must immediately suggest ventricular tachycardia. Instead, the rate of 150, plus the history of AF, suggested atrial flutter.

This strip was obtained: Apparent Wide Complex Tachycardia at a rate of 280 What do you think? 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.

There is a narrow complex tachycardia at a rate of 130. ECGs: there is a regular narrow complex tachycardia still at a rate of exactly 130, with no P-waves and also no change since the prehospital ECG. Leads II and aVF appear to have flutter waves. I diagnosed atrial flutter with 2:1 conduction. Is is sinus?

First, we have a narrow-complex, regular tachycardia, with a rate of about 135-140. This narrows our differential for the rhythm down to sinus tachycardia, paroxysmal supraventricular tachycardia (PSVT, or SVT), and atrial flutter. They are flutter waves, and the rhythm is 2:1 atrial flutter.

There are 2 atrial "bumps" for every QRS. Here I put arrows: Arrows shows slow atrial flutter waves. The PEARL is that recognition of a longer-than-expected P wave in a supraventricular tachycardia should bring to mind the “Bix Rule” ( See My Comment at the bottom of the page in the August 3, 2018 post in Dr. Smith's ECG Blog ).

The principal d ifferential d iagnosis i s similar to what we derived in the October 16, 2019 Case : i ) Sinus Tachycardia ; ii ) Reentry SVT ( either A VNRT if the reentry circuit is contained within the normal AV nodal pathway — or A VRT if an accessory pathway is involved ) ; iii ) Atrial Tachycardia ; or iv ) Atrial Flutter.
