[ECG changes in dextran intolerance (author's transl)]

In a 46-year-old patient following infusion of 5-10 ml of dextran ECG changes resembling those of infarction occurred together with severe left-sided chest pain, tachycardia, and an immeasurably low blood pressure. Rapid recovery occurred and normalisation of the ECG within an hour without signs of an intermediate phase. On these grounds it can be assumed that these previously unrecognised changes are probably the expression of a short-term coronary perfusion disturbance as part of an anaphylactoid reaction of the intima.
