This narrows our differential for the rhythm down to sinus tachycardia, paroxysmal supraventricular tachycardia (PSVT, or SVT), and atrial flutter. The patient’s history is notable for paroxysmal atrial fibrillation, which raises clinical suspicion for atrial flutter, since these two entities frequently coexist on a spectrum.

The WCT is interrupted by a series of variable-morphology QRS complexes, with atrial flutter waves note in II, III, and aVF. Detail of Flutter waves The rate of the flutter waves matches the rate of the WCT (about 200/m), proving that the presenting WCT had been 1:1 atrial flutter.

The ECG was interpreted as showing atrial flutter with 2:1 conduction. 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. She presented to the emergency department after a couple of days of chest discomfort.

I have used this to educate our residents, and I think they find it useful. Summary of ED Approach to Syncope Please excuse the formatting problems, which I have not been able to fix! It is NOT a structured review or meta-analysis. And when you see the list of patients who had adverse events, 26 of 39 were identified in the ED.

Possible but, again, the QRS morphology is atypical 3) Atrial Flutter with 2:1 conduction and "aberrancy". 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.
