Abstract:
Electrocardiographic changes due to ethylene glycol toxicity are described in a 37-year-old woman who presented with intentional overdose. She received prompt treatment with dialysis and fomepizole, which reversed profound metabolic acidosis. ST-elevation in leads I, aVL, and aVR were observed 87 h after admission along with diffuse repolarization abnormalities. Coronary angiography found no evidence of coronary artery disease, and echocardiogram revealed normal left ventricle size and a mildly hypokinetic basal inferior wall. Diffuse repolarization abnormalities persisted for several days. Review of literature supports the diagnosis of myocarditis induced by toxic metabolites of ethylene glycol in context of hepatic and renal failure.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
