Emergency Department ECG
Cardiac Cath Report
LM- Normal caliber, patent
LAD- Normal caliber, transapical, diffuse mild luminal irregularities. D1large, patent
LCx- Normal caliber, proximal patent, OM 1 large, mild disease. OM 2 large, 80% mid stenosis. AV groove LCx small patent
RCA- Large, dorminant, proximal- 80% hazy stenosis, mid and distal moderate diffuse disease. PDA 95% mid stenosis.
Stent placed to mid RCA
- 40-50% of all myocardial infarctions.
- more favorable prognosis than anterior myocardial infarction
- Up to 40% of patients with an inferior STEMI will have a concomitant right ventricular infarction. These patients may develop severe hypotension in response to nitrates and generally have a worse prognosis.
- Confirmed with Right sided ECG, Elevation in V4R
- Up to 20% of patients with inferior STEMI will develop significant bradycardia due to second- or third-degree AV block. These patients have an increased in-hospital mortality (>20%).
- ECG findings
- ST elevation in leads II, III and aVF
- Reciprocal ST depression in aVL (± lead I)
- RCA (80%): Elevation in III > II, Reciprocal depression in I
- LCx (20%): Elevation in III = II, No reciprocal depression in I
