Atrial Flutter Electrophysiology Ischemia

The ECG was interpreted as showing atrial flutter with 2:1 conduction. Are you confident there is no ischemia? 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. Do you agree with this strategy?

The Differential Diagnosis is: SVT with aberrancy(#) [AVNRT vs. WPW (also called AVRT*)] Atrial flutter with 1:1 conduction, with aberrancy VT coming from the anterior fascicle ( fascicular VT )@ *AVRT = AV Reciprocating Tachycardia (Tachycardic loop that uses both the AV node and an accessory pathway.

There is a large peaked P-wave in lead II (right atrial enlargement) There is left axis deviation consistent with left anterior fascicular block. There is no evidence of infarction or ischemia. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. Try adenosine.

Evidence of acute ischemia (may be subtle) vii. Electrophysiologic studies were performed in selected patients only as clinically appropriate. Arrhythmias as a cause of syncope were diagnosed by cardiac monitoring or electrophysiologic testing. 2nd or 3rd degree AV blocks or sinus pause of at least 2 seconds iv. Left BBB vi.

No evidence for ischemia jumps out. Cardioversion is most beneficial for reentrant arrhythmias ( e.g. VT, atrial flutter, AVNRT, atrial fibrillation) because it terminates the reentry circuit. He said he had had three episodes of chest pain that day while urinating. ECG 1 What do you think?
