With experience, applying the P s, Q s, 3 R Approach ( See ECG Blog #185 ) — to formulate the above steps in our initial assessment of the rhythm in Figure-1 can ( should ) be completed in less than 30 seconds! These are reviewed in ECG Blog #343. What about the 1 2- L ead E CG ? The QTc is not overly prolonged.

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.

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.

There is the appearance of STE in inferior leads II, III, and aVF (with STD in aVR), but this is entirely due to flutter waves which are only seen in those leads. Also, the atrial flutter in this case is relatively slow like in many other cases we've shown. Atrial Flutter with Inferior STEMI? Is this inferor STEMI?

Written by Jesse McLaren A 65 year old with a history of atrial flutter, CABG and end-stage renal disease on dialysis presented with 3 days of fluctuating chest pain, which was ongoing at triage. The first ECG was labeled “anterior subendocardial ischemia”, but subendocardial ischemia does not localize. What do you think?

Here I put arrows: Arrows shows slow atrial flutter waves. I favor the P s, Q s, 3 R Approach — as a simple acronym to facilitate recall of the 5 KEY Parameters for rhythm interpretation ( See My Comment in the October 25, 2022 post in Dr. Smith’s ECG Blog ). These mimic ST Elevation. But there is no STE. Would you give lytics?

If it is slow Atrial flutter with 1:1 conduction, it should slow the conduction and reveal the flutter waves. This is the exact rate one expects with slow atrial flutter and it is why slow atrial flutter can be so dangerous: it conducts 1:1, with fast ventricular rates. Rate 120, flutter rate 240.
