There is a regular narrow complex tachycardia. Thus, it is supraventricular tachycardia. It is important to remember that SVT includes Sinus Tachycardia! Sometimes even Wide Complex Tachycardia is Sinus. See this case in which Lewis leads were necessary to figure this out: Wide Complex Tachycardia.

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.

First, we have a narrow-complex, regular tachycardia, with a rate of about 135-140. This narrows our differential for the rhythm down to sinus tachycardia, paroxysmal supraventricular tachycardia (PSVT, or SVT), and atrial flutter. They are flutter waves, and the rhythm is 2:1 atrial flutter.

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.

Are the wide complexes due to a supraventricular rhythm (AVNRT or Atrial flutter or atrial fib) with aberrancy? Or are they due to ventricular tachycardia (VT). The rhythm alternates between a wide complex (first 4 beats, and beats 16-28) and narrow complex (beats 5-15). There are no P-waves. Sinus P waves are absent.

RBBB is no longer seen after conversion to sinus rhythm — which supports our suspicion that the intermittent RBBB conduction seen every-other-beat during the tachycardia ( in Figure-1 ) was rate-related. Note that QRS morphology after conversion to sinus rhythm is very similar to QRS morphology of odd-numbered beats during the tachycardia.

Since the rate of atrial activity with flutter in adults is most often very close to 300 /minute ( ie, usual range for atrial activity ~250-350/minute ) — AFlutter with 2:1 AV conduction typically results in a regular ventricular rate of ~140-160/minute.
