Two recent interventions have proven in randomized trials to improve neurologic survival in cardiac arrest: 1) the combination of the ResQPod and the ResQPump (suction device for compression-decompression CPR -- Lancet 2011 ) and 2) Dual Sequential defibrillation. So, your next step is to Trace it down, and Copy it over".

Because the patient had no chest pain or shortness of breath, they were initially diagnosed as gastroenteritis. But because the patient had no chest pain or shortness of breath, it was not deemed to be from ACS. Potassium was normal. Cardiology did not think it was "STEMI", but repeated the troponin. Take home 1.

Subendocardial Ischemia from another Cause ( ie, sustained tachyarrhythmia; cardiac arrest; shock or profound hypotension; GI bleeding; anemia; "sick patient" , etc. ). Having looked for negative U waves in patients with chest pain over a period of decades — I'll emphasize that this is not a common finding.

Apparently he denied chest pain. About two hours after admission, he suffered a cardiac arrest (whether it was VF/VT or PEA is not available) and expired. JAMA 2000) showed that 1/3 of patients with STEMI, and 1/3 of patients with NSTEMI, present without chest pain. Here is his first ED ECG: What do you see?

Unfortunately — the patient abruptly developed hypoxemia, followed by cardiac arrest with PEA. It was thought that this action precipitated the patient's desaturation, and led to his cardiac arrest. The plan was to proceed as soon as possible with aortic valve replacement. He could not be resuscitated.
