He had this ECG recorded. He was rushed by residents into our critical care room with a diagnosis of STEMI, and they handed me this ECG: There is sinus tachycardia with ST elevation in II, III, and aVF, as well as V4-V6. But, remember, we do not evaluate and treat ECGs, we evaluate and treat patients.

Other causes of sickling: acidosis, dehydration, inflammation, infection, fever, and blood stasis Sickling leads to vascular occlusion, end-organ ischemia, and decreased RBC lifespan, which, in turn, leads to pain crisis, acute anemia, sequestration, infection, and acute chest syndrome (ACS.) ECG: Evaluate for ischemia, right heart strain.

An immediate 12-lead EKG was obtained: There is ST elevation in leads aVR and V1, with marked ST depression in I, II, III, aVF, V3-V6. Smith comment: This patient did not have a bedside ultrasound. The ECG cannot diagnose the etiology of ischemia; it only the presence of ischemia, from whatever etiology. What should be done?

Here is her EKG: What is unusual about this? Her bedside cardiac ultrasound was normal We decided to cardiovert her since the time of onset was very recent.

Consider IV access and early IV fluids in those at risk for dehydration and intra-abdominal infections. Jeff: Tachycardic patients should make you concerned for hypovolemia 2/2 dehydration, sepsis, leaks, and blood loss. Consider performing a RUSH exam (that is rapid ultrasound for shock and hypotension) to identify the cause.
