QUESTIONS: Is this rhythm too fast to be sinus tachycardia? Are flutter waves hidden within the QRS and T waves? 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).

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. Figure-2: I've labeled the initial ECG in today's case. And a Final Tracing.

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.

male with pertinent past medical history including Atrial fibrillation, atrial flutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Description : Regular Wide Complex Tachycardia at a rate of about 160.

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. The ECG was interpreted as showing atrial flutter with 2:1 conduction. Answer : The ECG above shows a regular wide complex tachycardia. The heart rate could be compatible with that of a 2:1 conducted atrial flutter.

There is a regular narrow complex tachycardia. Thus, it is supraventricular tachycardia. It is important to remember that SVT includes Sinus Tachycardia! See many cases with use of Lewis Leads on this blog: Case continued The providers jumped to conclusions and gave adenosine. His pulse was 186. I do not have the strips.

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.
