The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Massive Transfusion for Motorcycle Collision with Hemorrhage, Troponin Elevated. Between 81-95% of life-threatening ventricular dysrhythmias and acute cardiac failure occur within 24-48 hours of hospitalization.

Side note: The differential of sudden persistent loss of consciousness with adequate hemodynamics is relatively short: seizure, intracranial hemorrhage, basilar artery occlusion. We have also shown several cases in which atrial flutter hides true, active ischemia. There was again no intracranial hemorrhage.
