?Benign? course and malignant clinical presentations of congenital long QT syndrome

This report describes the "benign" clinical course of a congenital long QT syndrome (LQTS) simulated acute coronary event in an 85 year old woman who had a history of recurrent syncope accompanied by numerous severe traumatic events from childhood. Her daughter died suddenly. LQTS was diagnosed on the basis of characteristic ECG findings, including a permanently prolonged QT interval, typical dynamic T-wave changes, and runs of torsades de pointes. A permanent DDDR pacemaker was implanted. Eighteen months after implantation there have been no further complaints of dizziness or syncope.
