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.

P utting I t A ll T ogether : — The Rhythm in Figure-1 What we have just described is the following: A regular WCT ( = W ide- C omplex T achycardia ) at a rate very close to 300/minute — without clear sign of atrial activity. Among the fast Supraventricular Rhythms: This is not AFib — because the rhythm is regular.

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. After atrial rhythm/SR was restored the patient slowly improved.
