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. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ).

This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. ECG met STEMI criteria and was labeled STEMI by computer interpretation.

lidocaine) can result in severe bradycardia or asystole (Weinberg, Sedowski and Alexander, below) The presence of accelerated idioventricular rhythm does not affect prognosis, and there is no definitive evidence that, if left untreated, the incidence of VF or death is increased. Do not treat AIVR. In fact, use of antidyrhythimcs (e.g.,

Also consider non-hemorrhagic volume depletion, dehydration : orthostatic vitals may uncover this [see Mendu et al. (3)]. Evidence of acute ischemia (may be subtle) vii. Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful. Left BBB vi.
