hours ECG: Not much change hs troponin I peaks at 500 ng/L 8 hours Next morning Urine drug screen: Amphetamine, Methamphetamine, Fentanyl, Fentanyl metabolite Formal Bubble Contrast Echocardiogram: Indications for Study: Silent Ischemia. Conclusion: Type II MI probable due to hypoxia and tachycardia from resp arrest and amphetamine use.

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. CLICK HERE — for the ESC/ACC/AHA/WHF 2018 Consensus Document on the 4th Universal Definition of MI, in which these concepts are discussed and illustrated.

This patient was reported to have distant heart sounds but was not hypotensive and did not have JVD according to documentation. Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. Beck’s triad only happens all 3 together in approximately 1/3rd of patients.

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., As I indicated above, in our cardiac arrest case, after pushing 40 mEq, the K only went up to 4.2

There is no definite evidence of acute ischemia. (ie, In both tracings — an exceedingly fast PMVT is documented. Simply stated — t he patient was having recurrent PMVT without Q Tc prolongation, and without evidence of ongoing transmural ischemia. ( Some residual ischemia in the infarct border might still be present.

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. These are the conditions which have to be considered or excluded as they can sometimes manifest Brugada pattern on ECG.
