Similarly, STEMI guidelines call for urgent angiography for refractory ischemia or electrical/hemodynamic instability, regardless of ECG findings. So there is now high pre-test probability + refractory ischemia + Modified Sgarbossa + dynamic ECG changes. The patient still had chest pain and a third ECG was performed.

If there is polymorphic VT with a long QT on the baseline ECG, then generally we call that Torsades, but Non-Torsades Polymorphic VT can result from ischemia alone. If cardiac arrest from hypokalemia is imminent (i.e., mEq of K pushed fast and circulated theoretically would raise serum K immediately by 1.0 mg/dL [1.03 0.16

They had had twice the rate of cardiac arrest and twice the in-hospital mortality[1] In another study of patients diagnosed with STEMI, those on dialysis experienced delayed reperfusion and double the mortality.[2] Circulation 2007 2. Instead, ECGs need to be interpreted in isolation and then applied to the patient. Khan et al.

Circulation, 117, 1890–1893. [3]: These include ( among others ) — acute febrile illness — variations in autonomic tone ( as may occur with syncope ) — hypothermia — ischemia or infarction — cardiac arrest — and electrolyte disorders ( especially hyperkalemia — but also hypokalemia/hyponatremia ).

Circulation, 117, 1890–1893. [3]: In addition to a spontaneous or induced Brugada-1 ECG pattern, criteria for B rugada S yndrome require one or more of the following: History of cardiac arrest, of polymorphoic VT, or of non-vagal syncope — positive family history of sudden death at an early age — a similar ECG in close relatives.

It is apparently fortunate that she had a cardiac arrest; otherwise, her ECG would have been ignored. Then they did an MRI: Patient underwent cardiac MRI on 10/4 that showed mildly reduced BiV systolic function. Circulation [Internet] 2017;135(16):1481–9. Circulation.
