Documents a case of sudden cardiac death from ventricular tachycardia in a patient with prolonged QT syndrome despite phenytoin therapy.
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.
Stephen C. Vlay (1984) studied this question.
