title: Refractory ventricular tachycardia and fibrillation in a patient with the prolapsing mitral leaflet syndrome: successful control with overdrive pacing.
abstract: A 56 year old man with the prolapsing mitral leaflet syndrome presented with syncope and recurrent ventricular tachycardia and fibrillation. Treatment with antiarrhythmic agents (lidocaine, procainamide and propranolol) was unsuccessful. Overdrive pacing, in combination with propranolol, successfully suppressed the arrhythmias, and the patient remains well after 15 months of follow-up.
