About 20 years subsequent to a thyroid operation, syncopes occurred in a 42-year-old male patient. A prolonged QT interval was seen in the ECG. Both calcium and magnesium concentrations were decreased (calcium 1.1 mmol/l, magnesium 0.6 mmol/l). There was hyperphosphataemia of 2.8 mmol/l with a parathormone level at the lower limit of normal. After substituting vitamin D and calcium the patient was discharged symptom-free.
