Part of the ST depression with deep T wave inversion in the lateral chest leads clearly reflects LV "strain" from the marked LVH — but despite the very large QRS amplitudes, this ST-T wave appearance looks disproportionate, suggesting at least a component of ischemia. Then there is the significant ST elevation we see in lead V1.

There is ST depression beyond the end of the wide QRS in I, II, aVF, and V4-V6, diagnostic of with subendocardial ischemia. It makes pulmonary embolism (PE) very likely. The small LV implies very low LV filling pressures, which implies low pulmonary venous pressure. First, what kind of arrest was this? What is going on?

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. 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.,

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia.

If a patient presents with chest pain and a normal heart rate, or with shockable cardiac arrest, then ischemic appearing ST elevation is STEMI until proven otherwise. The estimated pulmonary artery systolic pressure is 37 mmHg + RA pressure. Normal estimated left ventricular ejection fraction lower limits of normal.

Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. Conduction and refractoriness alternans may be seen with WPW-related as well as AV Nodal-dependent reentr y tachycardias — atrial fibrillation — acute pulmonary embolus — myocardial contusion — and severe LV dysfunction.

The patient was unconscious BEFORE the cardiac arrest, at the same time that she had strong pulses. Therefore, cardiac arrest is NOT the etiology of the coma. she had severe pulmonary edema.
