Acute selenium toxicity
Acute toxicity presents with acute respiratory distress syndrome, myocardial infarction, renal failure, vascular symptoms such as tachycardia and flushing of the face, as well as neurological features including tremors, irritability, and myalgia. Echocardiogram (ECG) abnormalities such as T-wave inversion and QT prolongation are often seen, with death often occurring as a result of refractory hypotension
Selenium toxicity is diagnosed based upon the presence of features of selenosis in humans, as there are no accurate biochemical or preclinical parameters.
