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.

In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. The rhythm is atrial fibrillation. The QRS complex is within normal limits.
