A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. DISCUSSION: The 12-lead EKG EMS initially obtained for this patient showed severe ischemia, with profound "infero-lateral" ST depression and reciprocal ST elevation in lead aVR.

It should be kept in mind that on occasions, beta-one agonist can result in increased ventricular ectopy e.g., in severe myocardial ischemia (by increasing myocardial demand), or sometimes with congenital long-QT syndrome. Smith, this can be accomplished by either using beta-one agonists or temporary transvenous pacing. J Am Coll Cardiol.

Now you have ECG and troponin evidence of ischemia, AND ventricular dysrhythmia, which means this is NOT a stable ACS. These are reperfusion T-waves (the same thing as Wellens' waves) Echocardiogram Regional wall motion abnormality-distal septum and apex. It they are static, then they are not due to ischemia.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. Between 81-95% of life-threatening ventricular dysrhythmias and acute cardiac failure occur within 24-48 hours of hospitalization. No cardiac MRI was done.

Formal echocardiogram showed normal EF, no wall motion abnormalities, no pericardial effusion. There were no dysrhythmias on cardiac monitor during observation. The patient proceeded to cath where all coronaries were described as normal with no evidence of any CAD, spasm, or any other abnormality. No more troponins were done.

We see a regular tachycardia with a narrow QRS complex and no evidence of OMI or subendocardial ischemia. But adenosine only lasts for seconds, and if the dysrhythmia recurs, then the adenosine is gone. Prevent the initiation of the dysrhythmia -- this can be done with a beta blocker by prenenting PACS 2. Adenosine worked.

A formal echocardiogram was completed the next day and again showed a normal ejection fraction without any focal wall motion abnormalities to suggest CAD. Cardiology was consulted and they agreed that the EKG had an atypical morphology for STEMI and did not activate the cath lab.
