The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate is about 130 bpm. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves. The ECG below was recorded.

That volatile course included Atrial flutter with RVR: == MY Comment , by K EN G RAUER, MD ( 7/11 /2023 ): == It's always rewarding to get "a Save!" — as in today's case, in which this 40-something year old patient with persistent VFib, followed by an extended complicated course — ultimately survived with intact neurologic status!

So this is an extremely slow atrial flutter with 2:1 conduction. Atrial rate 146, ventricular rate 73. I suspect that the amyloid slows the conduction of the atrial flutter. It turned out that he had a history of slow atrial flutter. It turns out that this patient has cardiac amyloidosis.

The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. There are no P waves preceding the QRS complexes, and no clear flutter waves. We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia.

The Differential Diagnosis is: SVT with aberrancy(#) [AVNRT vs. WPW (also called AVRT*)] Atrial flutter with 1:1 conduction, with aberrancy VT coming from the anterior fascicle ( fascicular VT )@ *AVRT = AV Reciprocating Tachycardia (Tachycardic loop that uses both the AV node and an accessory pathway.

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).

Cardioversion is most beneficial for reentrant arrhythmias ( e.g. VT, atrial flutter, AVNRT, atrial fibrillation) because it terminates the reentry circuit. Atrial tachycardia can occasionally be due to reentry, but reentrant circuits usually have a more stable cycle length without so much beat to beat variability.

Smith comment-2: Another adverse effect from flecainide is atrial flutter with 1:1 conduction (if you happen to go into atrial flutter, the flecainide slows the flutter rate such that it is slow enough to conduct throught the AV node at 1:1 and you can end up with a ventricular rate of 220!! and Brugada syndrome.

I do not see flutter wave baseline, and again the QRS morphology is not typical for a supraventricular rhythm. See this case, for example: A Relatively Narrow Complex Tachycardia at a Rate of 180.
