She reports that she is now unable to vagal out of her palpitations and is having shortness of breath and dull chest pain. But adenosine only lasts for seconds, and if the dysrhythmia recurs, then the adenosine is gone.

Sinus tach is often misinterpreted as a dysrhythmia. With OMI, all you know is that your patient has some nonspecific chest pain, SOB, shoulder pain etc. They often have good ejection fraction and tolerate the dysrhythmia quite well. 2) PSVT with "aberrancy" (atypical RBBB+LAFB).
