Documented sudden cardiac death in prolonged QT syndrome
S. C. Vlay, G. I. Mallis, E. J. Brown Jr and P. F. Cohn
Documentation of the mechanism of sudden death is described in a patient
with a prolonged QT interval. Ventricular tachycardia was initiated by a
ventricular premature beat (VPB) with a prematurity index similar to
previous isolated VPBs. This event occurred despite the fact that the
patient was receiving phenytoin sodium, a drug known to shorten the QT
interval.
