Cardiac repolarization indices in epilepsy patients.

Objectives: Although epilepsy may be associated with an increased risk for sudden cardiac death, its effects on Q-T intervals has not been established.

Methods: To determine whether changes in Q-T interval duration (QT(max c), QT(min c)) and dispersion (QT(D c)) occur in epileptic patients, we retrospectively studied 40 consecutive patients (age: 36.1 +/- 22.
