A 40-something presented after attempted prehospital resuscitation with persistent Ventricular Fibrillation

Dr. Smith's ECG Blog

My interpretation was: RBBB with hyperacute T-waves in V4-V6 that are all but diagnostic of LAD occlusion vs. post ROSC ischemia. Formal Echocardiogram: Normal left ventricular size and wall thickness. The patient had ROSC and maintained it. A 12-lead ECG was obtained: What do you think?

Back to basics: what is this rhythm? What are your options for treating this patient?

Dr. Smith's ECG Blog

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. The differential of a regular narrow QRS tachycardia is sinus tachycardia, SVT, and atrial flutter with regular conduction. There are no P waves preceding the QRS complexes, and no clear flutter waves.

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. "Due The echo was normal.

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. Later, he underwent a formal echocardiogram: Very severe left ventricular enlargement (LVED diameter 7.4 H eart R ate C an H elp !

Evidence of acute ischemia (may be subtle) vii. ST segment and T wave abnormalities consistent with or possibly related to myocardial ischemia. And these findings come from OESIL , EGSYS , and Sarasin studies: i: Non-sinus rhythm ii: SVT or VT (obviously, and this makes for an abnormal vital sign anyway) iii. Left BBB vi. LVH or RV d.

That said there were no clinical symptoms or ECG findings suggestive of ongoing ischemia. It is reasonable to perform an echocardiogram to evaluate LV function. You have given IV MgSO4 a fast acting -blocker and IV amiodarone bolus and infusion. The possibility of an ischemic cause of the ventricular arrhythmia has to be considered!
