I say this for the simple reason that to pick any of the above 4 choices — is to imply with 100% certainty that you know the answer ( or, as is implied in the title of today’s Blog post — this would be premature closure). ECG Blog #240 — The regular SVT. ECG Blog #229 — Why is AFlutter so commonly overlooked? s in Figure-2 ).

By the P s, Q s, 3 R Approach ( See ECG Blog #185 ): The rhythm is fast and QRS complexes are R egular. PEARL # 4: As emphasized in ECG Blog #204 , in which I review derivation of the bundle branch blocks — RBBB is a terminal conduction delay.

NOTE: The ECG in Figure-1 has been recorded at the usual 25mm/second speed — but with the Cabrera format ( Please see my Editorial Note near the top of the page in ECG Blog #365 for review of the basics of this recording system ). PEARL # 3: Atrial Flutter with 1:1 AV conduction is rare! ECG Blog #287 — More on AFlutter.

As discussed in detail in ECG Blog #240 — the term, “SVT” — refers to any supraventricular rhythm (ie, with origin at or above the AV node ) that manifests a rate of ≥100/minute. By this definition, a variety of rhythms may qualify as “SVTs” — including sinus tachycardia, atrial flutter or fibrillation, MAT, AVRT/AVNRT, among others.

As always — I like to start by focusing on the long lead rhythm strip — which shows a bigeminal rhythm — in that there are repetitive 2-beat groups ( See ECG Blog #232 for review of the concept of “bigeminy” ). PEARL # 1: As discussed in ECG Blog #232 — it helps to consider the differential diagnosis of a bigeminal rhythm.

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. I reviewed the concept of Echo beats in ECG Blog #239.

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. I'd add the following thoughts to Dr. Smith's discussion.
