title: Plasma 10-hydroxynortriptyline and ECG changes in elderly depressed patients.
abstract: Among 18 elderly depressed patients given ECGs before and during nortriptyline treatment, plasma E-10-hydroxynortriptyline and the sum of E-10-hydroxynortriptyline and nortriptyline distinguished the group with conduction/repolarization effects. Plasma nortriptyline, age, drug dose, and baseline cardiovascular status did not.
