✦ Synopsis

several beats should therefore be examined in each lead. Since the Q-Tc can vary in different EKG leads, a normal Q-Tc measured on a single EKG lead as part of an EEG examination does not rule out Q-Tc prolongation.

Bricker and colleagues 18, 151 emphasized that "Q-T interval prolongation is more subtle than striking on the [EKG] and must be looked for specifically." Evaluation of the EKG data contained in the EEG examinations of our 2 patients would have led to an earlier diagnosis of the Romano-Ward syndrome. We suggest that electroencephalographers should be aware of the syndromes of hereditary Q-T interval prolongation and that the Q-Tc should be calculated in young patients with syncope, seizures precipitated by exercise and excitement, or a family history of similar episodes and sudden death. Twelve-lead EKG evaluation of patients with this history is always indicated.
