Long term follow up of long QT syndrome treated by overdrive pacing.

Long term follow up of a patient with idiopathic long QT syndrome is described. A 5 year old girl was admitted with attacks of unconsciousness. Epilepsy was diagnosed and the patient was treated with anticonvulsants. During other episodes, ECG study showed torsades de pointes. The patient was treated with beta blockers, stellectomy without success, and later with overdrive pacing. The young woman is now 43 years old and in good health.
