[Rare cause of long QT and resuscitation-requiring torsade de pointes tachycardia].
A 62 year old patient underwent an intraoperative pancreas biopsy because of a pancreas head process. On 13(th) and 20(th) postoperative day a short syncope episode occurred. On that days calcium blood levels were 1,82 and 1,74 mmol/l, respectively. On 13(th) postoperative day QT(c) interval was 565 ms. On 26(th) postoperative day the patient was resuscitated because of torsade de pointes tachycardia. His actual calcium blood level was 1,47 mmol/l and QT(c) interval 627 ms. An extensive diagnostic work-up revealed no evidence of cardiac disease. After calcium substitution QT interval normalised. During a follow-up period of 16 months the patient remained without symptoms.
