Here is his 12-lead ECG: The computer reads supraventricular tachycardia. It is atrial flutter with 2:1 conduction. There are clear flutter waves in lead II across the bottom. Adenosine simply blocks the AV node so that there is no QRS to hide the flutter waves, and they become obvious. What is it?

PEARL # 3: At this point — the most time-efficient step for solving today's rhythm will be to determine the nature of atrial activity. C ASE C onclusion : I lack detailed follow-up from today's case — other than knowing that the Atrial Tachycardia was controlled. ECG Blog #138 — AFlutter vs Atrial Tachycardia.

By this definition, a variety of rhythms may qualify as “SVTs” — including sinus tachycardia, atrial flutter or fibrillation, MAT, AVRT/AVNRT, among others. Why Isn’t this a Run of Atrial Tachycardia? — ECG Blog #138 — AFlutter vs Atrial Tachycardia.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). This patient very likely has some form of idiopathic ventricular tachycardia. Of the ventricular outflow tract tachycardias (RVOT-VT) makes up 80-90%.
