It should be emphasized here that this is a presentation of high-pretest probability for Acute Coronary Syndrome (ACS). ACS and hyperkalemia both have lethal downstream consequences, so it is imperative for the clinician to acclimate to the presentation, or developing, features of each. ECG's are difficult. 2] Costanzo, L. Physiology.

RBBB + LAFB in the setting of ACS is very bad. Some patients have baseline RBBB with LAFB, but in patients with likely ACS, these are associated with severe infarction with cardiac arrest, cardiogenic shock or impending shock. Patients with ACS and RBBB/LAFB usually have a left main vs. proximal LAD. Learning Points: 1.

AC and DC shocks may result in different injury patterns. Significant injuries can occur even in the absence of extensive burns or other signs of external injury.

Smith: If this is ACS (a big if), t his is just the time when one should NOT use "upstream" dual anti-platelet therapy ("upstream" means in the ED before angiography). History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. Anything more on history?

Opioids do not cause ACS but they can exacerbate hypoxia in patients with ACS. Older children and adults usually present with ACS 2-3 days after hospitalisation due to pulmonary infarction (in situ sickling), hypoventilation due to rib infarction (which may be exacerbated by recent narcotic administration) or fat embolism.

As a result, even before looking at this patient's initial ECG — he falls into a high -prevalence likelihood group for ACS ( for an A cute C oronary S yndrome ). We therefore need to assume and rule "out" ACS — more than having to rule it "in". The "onus of proof" remains on us as medical providers to objectively rule out ACS.
